心动过缓——心动过速综合征(简称慢——快综合征),是病窦综合征(SSS)的晚期表现之一。本综合征由于窦房结功能低下,而引发异位的快速心律,因而药物治疗非常棘手。我院用VVI型起搏器治疗了该综合征16例,其中男3例,女13例,年龄35～69(58±13.4)岁。心电监护及心电图记录:心室率平均最慢为40次/分,最快达150次/分。16例病人均有昏厥史,其中10例病人入院后进行了食管心房调搏检查(另6例病人因病情较重未予进行),均诊断为SSS。入院后经药物 Bradycardia - tachycardia syndrome (referred to as slow - fast syndrome), is one of the advanced manifestations of sick sinus syndrome (SSS). The syndrome because of sinus node dysfunction, and ectopic euthyroidism caused by rapid, so drug treatment is very tricky. The hospital with VVI pacemaker treatment of the syndrome in 16 cases, including 3 males and 13 females, aged 35 to 69 (58 13.4) years of age. ECG monitoring and ECG records: the average ventricular rate was the slowest 40 times / min, the fastest up to 150 beats / min. All 16 patients had a history of syncope. Ten patients underwent esophageal atrial pacing after admission (the other 6 patients were not under severe conditions) and were diagnosed as SSS. After admission by the drug
