Leadless pacemakers have become a major breakthrough in the management of bradyarrhythmia as an attractive alternative to the standard transvenous pacemakers, but safety and long-term outcomes of the new Micra-AV, which is capable guarantee atrioventricular (AV) synchrony, have been poorly described. Hence, we describe how we managed a 57-year-old patient who developed pacemaker syndrome due to significant Micra-AV dyssynchrony. This case emphasizes how leadless pacemaker AV synchrony could be overestimated, thereby requiring a stepwise process leading to adequate device reprogramming. Holter-ECG monitoring and exercise test resulted to be valuable tools for an early detection of inadequate AV synchrony, integrating and completing device reports.
