Increased heart rate caused by atrial pacing with the closed-loop stimulation function prevented micturition syncope

A 70-year-old man had been experiencing syncope several times a year. We implanted a DDD pacemaker with closed-loop stimulation (CLS) function. When he urinated early in the morning, his increased atrial pacing rates elevated his heart rate (HR) during and after micturition. After implantation of th...

Description
Summary:A 70-year-old man had been experiencing syncope several times a year. We implanted a DDD pacemaker with closed-loop stimulation (CLS) function. When he urinated early in the morning, his increased atrial pacing rates elevated his heart rate (HR) during and after micturition. After implantation of the DDD-CLS mode, he did not experience symptoms. In contrast, in the DDD-R mode, his intrinsic HR changed to atrial pacing after micturition but decreased to the basal rate within 2 min, and he experienced a sense of cold perspiration and presyncope. Increased HRs caused by atrial pacing with the CLS function were useful in the prevention of micturition syncope.
