83例非冠心病受检者同步记录M型超声心动图、心音图、心电图以及(27例左室肥厚者)心尖搏动图,并于7天内记录12导联心电图,分析左室功能和心电图表现之间的关系.按心电图表现受检者分成:10例健康志愿者(N组),15例左室肥厚(电压标准,H组),20例左室肥厚伴劳损(S组),38例U波倒置伴左室肥厚和劳损(U组).后三组73例内有:20例肥厚型心肌病,29例主动脉瓣狭窄和/或关闭不全,10例高血压性心脏病等.各例均为窦性心律且无房室传导异常.正常U波为正向(U_(?VR)例外),波幅低于其前的T波.两波波峰相距150ms或 Eighty-three subjects with non-coronary heart disease underwent simultaneous recording of M-mode echocardiography, phonocardiogram, electrocardiogram and apical beating of 27 patients with left ventricular hypertrophy. A 12-lead electrocardiogram was recorded within 7 days to analyze left ventricular function and electrocardiogram (N = 10), left ventricular hypertrophy (n = 20), left ventricular hypertrophy (n = 20), left ventricular hypertrophy U-waves were inverted with left ventricular hypertrophy and strain (Group U). The latter three groups included 73 patients with hypertrophic cardiomyopathy, 29 with aortic stenosis and / or insufficiency, and 10 with hypertensive heart disease. Each case was sinus rhythm and no abnormal conduction of atrioventricular normotensive normal U wave (U _ (? VR) exception), the amplitude is lower than the previous T wave.The two wave peaks 150ms or
