Abstract

A middle‐aged gentleman with an idiopathic dilated cardiomyopathy, drug‐refractory sustained ventricular arrhythmia, and high‐degree AV block was managed with an automatic implantable cardioverter‐defibrillator (AICD) and a Cordis Multicor II VVI pacemaker. During a routine follow‐up visit, the pacemaker threshold was determined. Seven seconds after reprogramming the Cordis pacemaker to the “stat” WI mode, the AICD discharged. The time to discharge after reprogramming (he pacemaker equalled (he previously determined AICD charge time. No other rhythm disturbance was documented and the rate with double counting of pacemaker stimulus and QRS complex was less than the triggering rate/or the AICD. In conclusion, the AICD can be triggered by pacemaker programming signals unrelated to subsequent peacemaker function.
