Abstract


ELT is a complication in patients with DDD pulse generators and intact ventriculo– –atrial conduction. Retrograde atrial depolarizations are sensed and then, after the appropriate A–V delay, the pacemaker delivers a stimulus to the ventricle. Thus, the pacemaker provides the antegrade conduction pathway for the reentrant circuit and the intrinsic conduction system of the heart provides the retrograde pathway. It generates a repetitive cycle of ventricular, retrograde P wave synchronized pacing. We describe a case of ELT in a fifty–year–old man with complete heart block and DDDR pacemaker implanted. ELT stopped by itself. Further observation confirmed the correct DDDR stimulation without ELT syndrome.
