为了探讨嘌呤化合物STR(Striadyne)对病态窦房结与正常窦房结的抑制作用是否有差异以及这种差异能否用于病窦综合征(SSS)的诊断,对55例病人进行了研究。根据临床表现,心电图和窦房结功能测定,病人分成三组,第1组:正常;第2组:SSS(Za组:明确的SSS;Zb组隐性SSS);第3组:迷走神经张力过高及/或对迷走刺激反应异常。病人均经肘静脉插入6极导
In order to investigate the differences in the inhibitory effect of purine STR (Striadyne) on sick sinus and normal sinus node and whether this discrepancy can be used in the diagnosis of sick sinus syndrome (SSS), 55 patients were studied. Patients were divided into three groups according to clinical presentation, electrocardiogram and sinoatrial node function, group 1: normal; group 2: SSS (group Za: definite SSS; group Zb: recessive SSS); Group 3: vagal tone High and / or unusual response to vagus irritation. Patients were inserted through the elbow 6 pole guide
