一般左心室肥大的心电图诊断标准是特异性高而敏感性低。有人曾提出将病人按年龄.性别分层后可改善诊断的敏感性.我们研究肥胖对心电图诊断左心室肥大的影响.以明确是否通过区分体型能够进一步提高心电图对左心室肥大的检出率.采用在对照组人群中得提的不同性别的左心室体质量指数的正常上限值.我们发现在100例高血压患者经超声心电图检查61例确认为左心室肥大.胸导联标准(S_(v1)+R_(v5)>3.5mV).肢体导联标准纯作正向波RⅠ(R—S值Ⅰ)+纯负
General ECG diagnosis of left ventricular hypertrophy is highly specific and low sensitivity. It has been proposed to stratify the patient by gender stratification can improve the diagnostic sensitivity.We study the impact of obesity on ECG diagnosis of left ventricular hypertrophy in order to make clear whether by distinguishing the body type can further improve the detection rate of ECG on left ventricular hypertrophy. We used the upper limit of normal of the left ventricular mass index for different sexes in the control group.We found that 61 cases of hypertensive patients were diagnosed as left ventricular hypertrophy by echocardiography.The standard of chest lead v1) + R_ (v5)> 3.5mV) .Standard pure lead RⅠ (R-S value Ⅰ) + pure negative
