This Holter-ECG comes from a 70-year-old physician with coronary artery disease. He is twelve months after PCI (RCA, RCX). Currently no symptoms (no dyspnea, no chestpain, no palpitations). You can see that an overview/section from a Holter- EKG, 3 channels are shown, strip width is 30 seconds. First you can see a sinus rhythm with frequent PVCs, then there is a transition to an accelerated idioventricular rhythm (AIVR) that lasts almost a minute in total.
