Sinus node dysfunction and AV block constitute the underlying pathology for the majority of patients receiving permanent pacemakers. The predominate arrhythmia is bradycardia, and although rarely life threatening, patients may present with severe symptoms such as syncope or acute heart failure. In these situations, patients are admitted to the critical care or telemetry unit for monitoring and treatment. It is the responsibility of the critical care nurse to have an understanding of the clinical manifestations of sinus node dysfunction and AV block and to initiate appropriate interventions for symptomatic arrhythmias.
窦房结功能障碍和房室传导阻滞是大多数接受永久性起搏器治疗患者的潜在病理基础。主要的心律失常是心动过缓，虽然很少危及生命，但患者可能会出现严重症状，如晕厥或急性心力衰竭。在这些情况下，患者会被收治到重症监护病房或遥测病房进行监测和治疗。重症监护护士有责任了解窦房结功能障碍和房室传导阻滞的临床表现，并对有症状的心律失常采取适当的干预措施。
