Four patients with different clinical conditions had transient cardiac standstill for periods of up to 22.5 seconds. All patients showed signs of cerebral ischemia and required cardiac resuscitation. In one patient, the standstill was thought to be the result of a transient increase in the vagal tone, and no long-term therapy was required. In the second patient, cardiac standstill occurred during hospitalization for impending myocardial infarction. Coronary arteriography followed by coronary artery surgery was performed, and there was no further episodes of standstill. In the third patient, standstill was probably related to long-term ingestion of propranolol hydrochloride, and was not observed after this medication was discontinued. In the fourth patient, standstill was the result of the sick sinus syndrome, and a permanent pacemaker was inserted. Standstill of both atria and ventricles may occur under different clinical settings, and management of arrhythmia should be guided by thf etiology of the arrhythmia.
四名患有不同临床病症的患者出现了长达22.5秒的短暂心脏停搏。所有患者均表现出脑缺血症状，且需要进行心脏复苏。在一名患者中，心脏停搏被认为是迷走神经张力短暂升高的结果，无需长期治疗。在第二名患者中，心脏停搏发生在因即将发生心肌梗死而住院期间。随后进行了冠状动脉造影及冠状动脉手术，此后未再出现心脏停搏发作。在第三名患者中，心脏停搏可能与长期服用盐酸普萘洛尔有关，停用该药物后未再观察到心脏停搏。在第四名患者中，心脏停搏是病态窦房结综合征的结果，已植入永久性起搏器。心房和心室的停搏可能在不同的临床情况下发生，心律失常的管理应以心律失常的病因学为指导。
