Six patients suspected to have "pacemaker syndrome" were studied with hemodynamic and electrophysiologic methods. Symptoms appeared after implantation of ventricular pacemaker (VVI). Mile symptoms such as dizziness and fatigue and severe symptom of heart failure were noted. The results of the study suggested that cardiac output decreases due to loss of atrial contribution to ventricular filling and also as a result of increase of systemic venous pressure. If the patient has V-A conduction, cardiac output will decrease further. Restoration of atrioventricular synchronization is essential in the treatment of the pacemaker syndrome.
对6例疑似患有“起搏器综合征”的患者进行了血流动力学和电生理方法研究。症状出现在植入心室起搏器（VVI）之后。观察到诸如头晕和疲劳等轻微症状以及心力衰竭的严重症状。研究结果表明，由于心房对心室充盈的贡献丧失以及体静脉压力升高，心输出量降低。如果患者存在室房传导，心输出量将进一步降低。恢复房室同步对于起搏器综合征的治疗至关重要。
