Abstract
- Objectives: In developing countries like India, patients with ventricular arrhythmias who were treated with antiarrhythmic drugs, in whom catheter ablation or implantable cardioverter-defibrillators (ICDs) were ineffective or contraindicated, are still obscured. Thus we aimed to evaluate the efficacy of mexiletine in patients with ventricular tachyarrhythmias/electrical storm, in whom standard treatment failed to prevent ventricular tachyarrhythmias. Methods: We performed a prospective, unicentric, observational study in patients with ventricular tachyarrhythmias treated with mexiletine in our institute from January 2019 to March 2021. The study population included all patients presented with recurrent ventricular tachyarrhythmias, with or without ICD. Results: Among the arrhythmic patients included in the study 20(80%) had monomorphic ventricual tachycardia (VT), 3(12%) had polymorphic VT and 2(8%) patients had ventricular fibrillation (VF). Patients were followed for 12 months, which showed only one patient had an episode of VT after initiating mexiletine (p<0.001). Total number of shocks and ATPs were significantly reduced compared to prior initiation of mexiletine (p<0.01 & p<0.001, respectively). Patients treated with mexiletine and both (mexiletine+amiodarone), did not have significant difference when compared to their long term efficacy. Survival analysis showed that the patients treated with mexiletine had increased survival rate compared to patients who were treated with other antiarrhythmic drugs. Conclusions: The study indicates that treatment with mexiletine may be effective and safe in patients with ICD and frequent ventricular arrhythmias and ICD shocks, regardless of the aetiology of heart disease.
