Atrioventricular blocks may be caused by a variety of potentially reversible conditions, such as ischemic heart disease, electrolyte imbalances, medications, and infectious diseases. Such causes must be always ruled out to avoid unnecessary pacemaker implantation. Patient management and reversibility rates depend on the underlying cause. Careful patient history taking, monitoring of vital signs, electrocardiogram, and arterial blood gas analysis are crucial elements of the diagnostic workflow during the acute phase. Atrioventricular block recurrence after the reversal of the underlying cause may pose an indication for pacemaker implantation, because reversible conditions may actually unmask a preexistent conduction disorder.
房室传导阻滞可能由多种潜在可逆转的情况引起，如缺血性心脏病、电解质失衡、药物和传染病。为避免不必要的起搏器植入，必须始终排除这些原因。患者管理和可逆转率取决于潜在病因。仔细询问患者病史、监测生命体征、心电图和动脉血气分析是急性阶段诊断工作流程的关键要素。潜在病因逆转后房室传导阻滞再次发生可能提示需要植入起搏器，因为可逆转的情况实际上可能会暴露出先前存在的传导障碍。
