一、实验目的本文对左室高电压运动员(实验组)与非左室高电压运动员(对照组)进行了心电图和超声心动图的测量,并计算出多种有关参数,试图进一步确定其临床意义.二、方法与对象本实验采用日本ALoka工厂生产的SSD-710型超声心动图仪和日本制(光电公司)心电图机.所有被测试人员均经体格检查,证实无心血管疾病.青年实验组为12名男性,平均年龄23.9岁(20～30岁),运动年限3～10年;中年实验组为8名男性,平均年龄50.5岁(40～55岁),运动年限15～20年以上.对照组均为心电图电压正常的运
First, the purpose of the experiment In this paper, left ventricular high voltage athletes (experimental group) and non-left ventricular high voltage athletes (control group) were measured by electrocardiogram and echocardiography, and calculated a variety of parameters in an attempt to further determine its clinical significance Second, the method and object In this experiment, Japan’s ALoka factory production of SSD-710-type echocardiography and Japan-made (Photoelectric Company) ECG machine .All the testees were physical examination, confirmed no cardiovascular disease.The young experimental group was Twelve males, mean age 23.9 years (20-30 years), exercise years 3-10 years; middle-aged experimental group of eight males, mean age 50.5 years (40-55 years), exercise years 15-20 years. Control group were normal voltage electrocardiogram transport
