Abstract

An asymptomatic 48-year-old gentleman presented for routine interrogation of his Medtronic dual chamber transvenous pacemaker. The device was implanted 4 years ago for post-operative intermittent high grade atrio-ventricular block following mechanical aortic valve replacement. As per our protocol, we performed a 12-lead electrocardiogram with and without magnet application. The unusual response elicited after application of magnet is mechanistically explained.
