Syncope caused by several factors, one of them is micturition syncope. Micturtion syncope generally recognized that alcohol drinking men who lost his consciousness after awaking from midnight sleeping, during or post standing urination, lose consciousness by vaso-vagal reaction accompany with urination. Here we experienced a 28-year-old female who showed micturition syncope. For 10 min of syncope, no response observed. According to personal history, 9 times for 9 months occurred. Syncope always occurred after urination while o'clock in a day was not definite. Autonomous and EEG response were normal, nothing happened by standing up test, and no hypotension status detected. Valsalva test and Aschner test were negative. Before urination, blood pressure (bp) was 140/90mmHg and heart rate was 103/min, when starting urination, heart rate decrease to 78/min, finished urination and stood up, the bp lowered 33mmHg. ECG showed alternative rhythms of usual and ventricular premature contraction, and returned to normal rhythm after 1 min. This alternative systole and lowered blood pressure might be the cause of micturition syncope.
