1. 正常心率:每分钟75次 健康成年人安静状态下,心率平均为每分钟75次。正常范围为每分钟60-100次。成人安静时心率超过100次/分钟,为心动过速;低于60次/分钟者,为心动过缓。心率可因年龄、性别及其他因素而变化,比如体温每升高1℃,心率可加快12-20次/分钟,女性心率比男性心率稍快,运动员的心率较慢,可低于每分钟 ...

阅读前须懂的几个基本问题: 1、各波形的意义 (1)P波:代表心房除极过程:故P波的异常常是代表心房的问题,例如一个COPD患者II导联P波振幅0.25mv,诊断右房肥大。 (2)PR间期:不等于PR段,而=P波+PR段。代表心房除极开始至心室开始除极,故其时间延长可见于房室传导阻滞。 (3 ...
