测定窦房结功能的方法,虽然有阿托品试验、异丙基肾上腺素试验、运动试验、窦房结恢复时间、窦房结传导时间等,但国内普遍开展的方法为前三种。这三种方法那一种最为理想可靠?只测一种方法或者三种方法都要测定?测定的结果与临床资料的相关程度如何?为了解答这些实际的临床问题,作者比较了对照组(健康正常人)与窦缓组(窦性心动过缓病人)应用上述三种方法测定的结果,现报道如下。材料与方法一、对象与分组: 对照组:20例,18～23岁青年学生,无心血管疾病及窦性心动过缓病史、心率均在60次/分以
The method of determining the function of the sinus node, although there are atropine test, isoproterenol test, exercise test, sinus node recovery time, sinus node conduction time, but the method commonly used in China for the first three. Which of these three methods is the most ideal and reliable? Only one method or three methods to be measured? The results of the test and clinical data related to how? In order to answer these actual clinical problems, the authors compared the control group (healthy Normal) and sinus bradycardia (sinus bradycardia patients) The results of the above three methods were measured, are reported below. Materials and Methods 1, Subjects and Groups: Control group: 20 cases, 18 to 23-year-old young students, no history of cardiovascular disease and sinus bradycardia, heart rate were 60 beats / min
