Dual chamber pacemaker
I have had a duel chamber pacemaker for about 6 years for complete heart block. All my previous ECGs have showed an atrial sensed ventricular paced rhythm. Now I have switched to an atrioventricular duel-paced rhythm which means my atrium is being paced all the time. Has anyone had this happen? What is the underlying physiology? I am having problems finding out caused this. Thanks for any help.
