以前横剖面的人群研究,已显示了心电图波型方面的年龄差异,包括老年人波的振幅较低和额面电轴左偏。为了在相同的人群中调查心电图随年龄的变化,本文分析“正常老化研究”组中440名健康男性每隔十年进行的心电图记录,旨在观察老化对心电图的影响。方法:440名健康男性是从“正常老化研究”组的成员中挑选出来的,这些人首次检查时的年龄为23岁到66岁,必须有两次相隔大约为十年的心电图描记。心电图测量包括 R、S 和 T 波振幅,额面电轴,和 P-R,QRS 以及 Q-T 时间。测量Ⅰ,Ⅱ和Ⅲ导联的 R 波振幅,采用这些导联中最大的振幅。测
Previous cross-sectional population studies have shown age differences in ECG wave patterns, including lower amplitude of the older wave and left-offset frontal axis. In order to investigate ECG changes with age in the same population, this paper analyzes electrocardiographic recordings of 440 healthy men in the “Normal Aging Study” group every 10 years to see the effects of aging on the ECG. METHODS: A total of 440 healthy men were selected from members of the “Normal Aging Study” group who were 23 to 66 years old at the first exam and had to have two ECG traces separated by approximately 10 years. ECG measurements include R, S and T wave amplitudes, frontal axis, and P-R, QRS, and Q-T times. Measure the R-wave amplitudes of leads I, II, and III using the largest of these leads. Measurement
