Cardiac arrest while straining during a bowel movement is not unusual in elderly patients. Sinus bradycardia caused by increased vagal tone can lead to severe myocardial and cerebral hypoperfusion with cardiac arrest. We describe a female postoperative patient who, while straining on a bedside commode, developed varying degrees of atrioventricular heart block, necessitating placement of a permanent pacemaker.
老年患者在排便时用力导致心脏骤停并不罕见。迷走神经张力增加引起的窦性心动过缓可导致严重的心肌和脑灌注不足，进而引发心脏骤停。我们描述了一名术后女性患者，她在床边便桶上用力排便时出现了不同程度的房室传导阻滞，因此需要植入永久性起搏器。
