Efficacy of closed-loop stimulation with epicardial leads in an infant with congenital atrioventricular block
Paediatric Cardiology and Cardiac Surgery Unit, S. Vincenzo Hospital, Contrada Sirina, 98039 Taormina, Messina, Italy
We present the case of an infant with a congenital atrioventricular block and sinus node dysfunction that was implanted with a pacemaker with physiological closed-loop stimulation (DDD-CLS) pacing mode with two epicardial leads. We have observed the response of DDD-CLS system with respect to conventional rate responsive accelerometer-based mode (DDDR): the atrial pacing percentage and the 24 h rate trend showed higher values during DDD-CLS compared with DDDR. In this patient, rate responsive feature seems preserved in DDD-CLS also using epicardial leads.
