Abstract

The presence of isolated interrupted inferior vena cava (IVC) is very rare. Though the occurrence of typical atrial flutter in this setting has recently been described, the use of 3-dimensional activation mapping to aid the management of such patients has not yet been described. We report the successful ablation of this arrhythmia in a 63-year-old woman using the superior route through the internal jugular vein with the help of a mapping system.

Abstract

We report a case of a 57 year-old man with a minute ventilation rate-response pacemaker and an inappropriate increase in his heart rate during a transthoracic echocardiography study. The increase in heart rate was due to interference between echocardiography and minute ventilation sensor. This was confirmed by a repeat echocardiogram, which reproduced the same effect and turning off the minute ventilation sensor stopped the tachycardia. We suggest that deactivating the minute ventilation sensor would avoid this interaction and electrophysiologists should be aware of this unusual electromagnetic interference phenomenon.
