应用烃静脉埋藏式心脏起搏器治疗69例老年人缓慢心律失常,与同期青中年患者67例相比较。房室传导阻滞水平以房室(?)分叉以下表现为束支阻滞型多见(P<0.05),病窦综合症以 B 型最多(P<0.05),心律失常的病因以冠心病、高心病多见(P<0.001)。47例(70％)临床上未查出任何器质性心脏病的证据,符合原发性传导束退化症或原因不明病窦综合症,并提出前者的诊断标准。 69 cases of elderly patients with chronic cardiac arrhythmia were treated with hydrocarbon pulse buried pacemaker, compared with 67 cases of young middle-aged patients in the same period.
