Abstract

Cardioverter-defibrillators are conventionally implanted under general anaesthesia. However, implantation under conscious sedation is being increasingly used. It has been shown that cardioverter-defibrillators can be implanted in a more pacemaker-like approach: under local anaesthesia for the surgical procedure, and with mild sedation for defibrillation threshold testing only. The aim of the present study was to compare local and general anaesthesia in defibrillation threshold testing and implantation of cardioverter-defibrillators.Forty patients were assigned to two groups: in the first 20 consecutive patients the cardioverter-defibrillator was implanted under general anaesthesia (GA), and in the subsequent 20 patients under local anaesthesia (LA). There was no significant difference between the two groups in regard of age, body weight, underlying disease, left ventricular ejection fraction, and NYHA classification. The defibrillation threshold was 13.7 +/- 5.5 J under local anaesthesia versus 10.7 +/- 4.7 J under general anaesthesia (n.s.). For defibrillation threshold testing 7.9 +/- 3.6 shocks had to be applied in patients under general anaesthesia versus 6.2 +/- 1.3 shocks under local anaesthesia (n.s.). Mean heart rate, arterial oxygen saturation and mean arterial blood pressure remained stable throughout defibrillation threshold testing, irrespective of the type of anaesthesia used. The duration of the surgical procedure was 62 +/- 16 min under GA and 60 +/- 14 min under LA (n.s.), however, the entire implantation procedure was significantly longer in patients under general anaesthesia than in those under local anaesthesia (124 +/- 24 min and 97 +/- 22 min, respectively, p0.005). There were no complications in either group and the procedure was well tolerated. With the use of local anaesthesia the cost of anaesthesia were reduced by 72%.Local anaesthesia in combination with mild sedation is as safe and well tolerated as general anaesthesia in cardioverter-defibrillator implantation. Lidocaine used for local anaesthesia does not adversely affect the defibrillation threshold. Device implantation in a pacemaker-like approach results in a significant reduction in total procedure time and costs, and facilitates scheduling of the procedure.

Abstract

The majority of patients with implanted cardioverter defibrillators (ICD) require antiarrhythmic (AR) drugs. ARs may increase defibrillation energy requirements. This study investigated the effects of lidocaine, ajmaline, and diltiazem on ventricular defibrillation energy needs. In 24 isolated rabbit hearts, the 50 and 80% successful defibrillation energy (ED 50 , ED 80 ) was calculated in four phases: predrug baseline condition (phase I), and phases 2, 3, and 4 with increasing concentrations of lidocaine, ajmaline, diltiazem (n = 18). Control experiments (n = 6) with only Tyrode's solution infusion indicated that the preparation was stable over time. Defibrillation energy requirements significantly (p < 0.05) increased with all ARs. Low, medium, and high lidocaine concentrations increased ED 50 and ED 80 to 146, 223, and 312% and 139, 207, and 285%, respectively. Ajmaline increased ED 50 and ED 80 to 133, 175, and 251% and 135, 208, and 285%, respectively. Diltiazem increased ED 50 and ED 80 by 175, 236, and 334% and 158, 212, and 286%, respectively. The results of this study demonstrate a dose-dependent increase in defibrillation energy requirements by using lidocaine, diltiazem, and ajmaline. In patients with ICDs, administration of these drugs might cause a critical increase in defibrillation energy requirements, resulting in device failure.

40. Electromagnetic interference by transcutaneous neuromuscular electrical stimulation in patients with bipolar sensing implantable cardioverter defibrillators: a pilot safety study.

Author

Abstract

Neuromuscular electrical stimulation (NMES) is a frequently applied therapy for the treatment of pain and a therapeutic option to increase thigh muscle strength and endurance capacity in patients with heart failure. Electromagnetic interference (EMI) by the signals with sensing of ICDs is possible. Eight patients with subpectoral ICD systems and different transvenous bipolar sensing leads were subjected to electrical stimulation of the neck and shoulder and of the thighs using different stimulation algorithms. EMI with ventricular sensing was detectable in three of eight subjects. EMI occurred during stimulation of the neck (n = 2) and thigh (n = 2). EMI by NMES with atrial sensing was seen in two of four subjects with dual chamber ICDs. The safety of peripheral NMES has to be individually tested as EMI can also occur in ICD patients with bipolar sensing. [ABSTRACT FROM AUTHOR]

41. Unexplained syncope in patients with structural heart disease and no documented ventricular arrhythmias: value of electrophysiologically guided implantablecardioverter defibrillator therapy.

Author

Abstract

Aims To evaluate electrophysiologically guided implantable cardioverter defibrillator (ICD) therapy in patients with syncope, structural heart disease and no documented sustained ventricular tachycardia (sVT). Methods and Results Programmed ventricular stimulation (PVS) was performed in 52 patients (age 62±10 years): 40 patients had ischaemic and 12 patients had idiopathic dilated cardiomyopathy. On PVS sVT and ventricular fibrillation were induced in seven and four patients, respectively, and two patients spontaneously experienced symptomatic sVT. These patients received an ICD (ICD group, n=13). Non-inducible patients were left on conventional therapy (non-ICD group, n=39). During 5±2.8 years five ICD patients received therapies, all appropriate. There were seven non-sudden deaths and overall survival analysis revealed no significant difference. Recurrent syncope occurred in five ICD and four non-ICD patients and did not correlate well with sVT. The positive and negative predictive values of PVS for tachyarrhythmias or sudden death were 36 and 98%, respectively. Conclusion Syncope per se does not necessarily herald a bad prognosis. PVS identifies high-risk patients. Induction of ventricular fibrillation with double or triple extrastimuli is of limited value. Patients with poor left ventricular function and bad clinical condition benefit most from an ICD. Syncope and sVT are not necessarily correlated during follow-up, which may merit consideration.

Abstract

Heart transplantation is an accepted therapeutic option for patients with end-stage heart disease. However, because the availability of heart donors fails to keep pace with the growing demand, increasing numbers of potential recipients are placed on the waiting list, resulting in longer waiting times. About 20% of patients die while awaiting heart transplantation. The majority die from progressive pump failure (46%), whereas about 30% of all deaths occur suddenly. Monitored terminal cardiac electrical activity in patients dying while awaiting transplantation reveals that bradyarrhythmias and/or electromechanical dissociation are involved in 68% of cases and ventricular tachyarrhythmias in 32% of cases. Patients with a history of aborted cardiac arrest are at highest risk for recurrent malignant arrhythmias. The implantable cardioverter defibrillator (ICD) is the most effective therapy for preventing sudden cardiac death from ventricular tachyarrhythmias. Pooled data from a total of 75 sudden death survivors listed for cardiac transplantation demonstrate that ICD therapy can be applied with low mortality, low morbidity, and high efficacy, with up to 94% of the patients receiving appropriate shocks during the waiting period. However, there is considerable concern that this early survival benefit conferred by the ICD may be nullified by the competing risk of death due to terminal pump failure, as the waiting list and waiting time to transplantation lengthens. In advanced heart failure, risk stratification for sudden tachyarrhythmic death is only of limited value. Therefore, although sudden tachyarrhythmic death appears to constitute only a minor fraction of total cardiac death in patients awaiting heart transplantation, prophylactic ICD implantation as on electronic bridge to transplant may be considered. To define conclusively the role of prophylactic ICD therapy in this setting, prospective randomized studies are needed. [ABSTRACT FROM AUTHOR]

44. Physiological variation in the termination window of re-entry tachycardia studied by non-invasive programmed stimulation.

Author

SCHMIDINGER, H. and SOWTON, E.

Abstract

In seven patients with re-entry tachycardias and the implanted antitachycardia device Tachylog (Siemens Elema, Sweden) the variation in the termination window related to posture and exertion was investigated. The investigations were performed on an outpatient basis utilizing the interactive pacing mode of the implanted unit. Six patients had supraventricular tachycardia and one patient had exercise-induced ventricular tachycardia. In all patients, double ventricular stimuli were necessary for tachycardia control. In the patients with supraventricular tachycardia, the termination window decreased significantly in the erect position (−46.5%, P<0.001) and in two patients it completely disappeared. Two patients could be studied during exercise. In one patient, exertion caused the termination window to shrink to 63% of its duration standing still, whereas in the other patient it widened to twice its value in the erect position. In the patient with ventricular tachycardia, whom we could study erect only, additional exercise caused the termination window to shrink on average 16.5%. These findings demonstrate that the termination window of re-entry tachycardia varies considerably with posture and exercise. This has important implications for the design of antitachycardia algorithms which will be reliably effective during daily life. Repeated non-invasive stimulation studies can be performed as an out-patient procedure allowing investigation of re-entry tachycardia under circumstances mimicking daily life.

45. Survival rate and causes of death in patients with pacemakers: dependence on symptoms leading to pacemaker implantation.

MÜLLER, Ch., CERNIN, J., GLOGAR, D., LACZKOVICS, A., MAYR, H., SCHEIBELHOFER, W., SCHMIDINGER, H., SCHUSTER, E., SEDLACEK, K., and KALIMAN, J.

Abstract

The survival rate of 2256 patients with pacemakers was analyzed. Patients paced for Adams-Stokes equivalents (e.g. dizziness) showed a significantly better survival rate than did patients with pacemakers implanted for Adam-Stokes attacks or heart failure (P < 0.0001). The estimated survival of the latter two groups did not differ significantly. Of the deceased patients who had received a pacemaker for the treatment of heart failure, 54% died due to this condition despite pacemaker implantation. The relative percentage of cases of sudden death after pacemaer implantation was high in the groups with Adams-Stokes attacks (12%) and Adams-Stokes equivalents (13%). In patients paced for Adams-Stokes attacks, sudden death occured more frequently in the first year after pacemaker implantation (P<0.015) than during the following years. Therefore, inreased efforts should be made to monitor patients carefully after pacemaker implantation to enable prompt detection of malignant tachyarrhythmias, probably the cause of sudden death in a substantial number of patients with pacemakers.

46. Cardiac arrhythmias.

Abstract

Objective To evaluate prospectively the safety and feasibility of the implantation of cardioverter/defibrillator systems under local anaesthesia. Conventionally, cardioverter/ defibrillator systems are implanted under general anaesthesia. With the development of single-lead trans venous unipolar cardioverter/defibrillator systems for sub-pectoral implantation a pacemaker-like approach for device implantation appears applicable. Methods Implantation of a single-lead transvenous unipolar cardioverter/defibrillator under local anaesthesia with sedation for defibrillation threshold testing was performed in 37 consecutive patients. The presenting arrhythmia was ventricular fibrillation in 13 patients, and monomorphic ventricular tachycardia in 24 patients. A 1% lidocaine solution was used for local anaesthesia, and midazolam was applied for sedation to perform defibrillation threshold testing. Arterial blood pressure, arterial oxygen saturation and heart rate were monitored throughout the procedure. The patient's tolerance of the implantation procedure was evaluated with a standardized questionnaire. Results The unipolar transvenous cardioverter/defibrillator system was implanted successfully in all patients under local anaesthesia. During defibrillation threshold testing, sufficient sedation was achieved with 1·2±3·7 mg midazolam. For determination of the defibrillation threshold 5·9±1·4 episodes of ventricular fibrillation were induced. The mean defibrillation threshold was 13·1±5·5 J, and the mean duration of the implantation procedure was 68±30 mm. Mean heart rate, mean arterial blood pressure and arterial oxygen saturation were not significantly different before and after defibrillation thresh old testing. Twenty-six patients (70%) were symptom-free throughout the implantation procedure; most of the remaining patients reported minor symptoms. There were no complications, and patients were discharged 2·2±0·7 days after implantation. In 12 patients, post-implant testing of the implantable cardioverter/defibrillators was performed successfully, without sedation, 2·8±1·4 days after as an outpatient procedure. Conclusion Single-lead unipolar transvenous implantable cardioverter/defibrillator systems can be safely implanted under local anaesthesia with mild sedation for defibrillation threshold testing. The procedure is well tolerated [ABSTRACT FROM PUBLISHER]

47. The impact of implantable cardioverter-defibrillators on mortality among patients on the waiting list for heart transplantation

Author

Grimm, M., Wieselthaler, G., Avanessian, R., Grimm, G., Schmidinger, H., Schreiner, W., Podczeck, A., Wolner, E., and Laufer, G.

Abstract

Implantable cardioverter-defibrillators were investigated for their impact on mortality in 228 consecutive heart transplant candidates on the waiting list for transplantation (207 patients without and 21 with implantable cardioverter-defibrillator therapy). The mortality rate in 207 patients without implantable cardioverter-defibrillator therapy was 23.2% and in 21 patients with implantable cardioverter-defibrillator therapy was 4.7%. In a Cox proportional hazards model for all 228 study patients (mortality while on the waiting list: 21.5%; transplantation rate: 54.8%), the absence of an implantable cardioverter-defibrillator was only a marginally significant predictor of mortality ( p = 0.079). However, the absence of an implantable cardioverter-defibrillator was a powerful predictor of mortality for a subgroup of 134 patients with high-grade ventricular arrhythmias on Holter electrocardiography (mortality while on the waiting list: 26.1%; transplantation rate: 54.5%; p = 0.022) and for a subgroup of 58 survivors of sudden cardiac death (mortality while on the waiting list: 22.4%; transplantation rate: 56.9%; p = 0.018). Implantable cardioverter-defibrillator therapy can be strongly recommended in transplant candidates with a history of sudden cardiac death. Recommendations for an expanded, prophylactic use of implantable cardioverter-defibrillator therapy in heart transplant candidates cannot be given. (J THORAC CARDIOVASC SURG 1995;110:532-9)

48. The influence of nitroglycerine on the inducibility of sustained ventricular tachycardia in coronary artery disease.

Author

Probst, P., Gottsauner-Wolf, M., Schmidinger, H., and Weber, H.

Abstract

To investigate the influence of nitroglycerine on the inducibility of sustained ventricular tachycardia, 11 patients with documented sustained ventricular tachycardia were studied (mean age 59 years, range 52–70 years, eight posterior wall infarctions, three anterior wall infarctions). After the induction of sustained ventricular tachycardia using a standard protocol (three ventricular premature beats triggered on the R wave, three ventricular premature beats to the refractory period during basic driving rate up to 180 beats min−1), 0.8 mg nitroglycerine was given and when the wedge pressure started dropping (after about 3 min) the EPS was repeated. The mode of the initiation of sustained ventricular tachycardia was almost identical before and after application of nitroglycerine. In addition the heart rate before (mean 186 beats min−1) and after nitroglycerine (mean 187 beats min−1) and the morphology of sustained ventricular tachycardia were the same. It is therefore concluded that anti-ischaemic interventions by nitroglycerine treating silent ischaemia and improving ventricular function respectively does not influence the initiation of sustained ventricular tachycardia during EPS. Silent ischaemia obviously does not play a role in sustained ventricular tachycardia and therefore anti-ischaemic interventions cannot be expected to influence the recurrence of sustained ventricular tachycardia.
