Abstract
Electrocautery has previously been reported to induce ventricular arrhythmias in rare cases.1–3 However, to our knowledge, induction or cardioversion of atrial arrhythmias has not been reported. We report a case of repeated cardioversion from atrial flutter to sinus rhythm during electrocautery in a patient with a dual-chamber pacemaker.
Highlights
Electrocautery has previously been reported to induce ventricular arrhythmias in rare cases.[1,2,3] to our knowledge, induction or cardioversion of atrial arrhythmias has not been reported
A patient with atrial flutter and a Sorin (MicroPortÔ) pacemaker, a MedtronicÔ 4076 (Medtronic, Minneapolis, MN) 52 cm lead in the right atrium and a 4076 58 cm lead in the right ventricle, underwent a pulse generator replacement without interruption of anticoagulation
It was noted incidentally that during cautery the rhythm converted from atrial flutter to sinus rhythm and subsequently reverted back to atrial flutter (Figure 1A)
Summary
Electrocautery has previously been reported to induce ventricular arrhythmias in rare cases.[1,2,3] to our knowledge, induction or cardioversion of atrial arrhythmias has not been reported. A patient with atrial flutter and a Sorin (MicroPortÔ) pacemaker, a MedtronicÔ 4076 (Medtronic, Minneapolis, MN) 52 cm lead in the right atrium and a 4076 58 cm lead in the right ventricle, underwent a pulse generator replacement without interruption of anticoagulation. The device was programmed in DDI mode and both leads were programmed in a bipolar configuration. The device was located in a subcutaneous pocket in a left anterolateral, prepectoral position.
