目的评价心电图中正向超射T波与左室肥厚的关系。方法采用日本产ECG-9130P同步描记十二导心电图,必要时增加振幅2倍分析,使用美国ATL-U6做超声心动图检查,对超声心动图检出左室肥厚、左室扩大的56例进行心电图分析,同时针对24例有正向超射T波者进行超声心动图检查。结果超声心动图检出左室肥厚、左室扩大的56例中心电图显示有左室肥厚18例,占32%,心电图有正向超射T波者,其中18例超声心动图明显有左室肥厚、左室扩大改变,符合率在75%。结论正向超射T波可提高心电图诊断左室肥厚的诊断率。
Objective To evaluate the relationship between positive T-wave and left ventricular hypertrophy in electrocardiogram. Methods Japanese ECG-9130P simultaneous tracing 12-lead electrocardiogram, if necessary, increase the amplitude of 2 times the analysis of the use of the United States ATL-U6 do echocardiography, echocardiography detected left ventricular hypertrophy, left ventricular enlargement in 56 cases ECG analysis, at the same time for 24 cases of patients with positive T wave ultrasound echocardiography. Results echocardiography detected left ventricular hypertrophy, left ventricular enlargement in 56 cases of electrocardiogram showed left ventricular hypertrophy in 18 cases, accounting for 32%, ECG positive T wave were positive, of which 18 cases of echocardiography significantly left ventricular Hypertrophy, left ventricular enlargement change, in line with the rate of 75%. Conclusion Positive T-wave ultrasonography can improve the diagnosis of left ventricular hypertrophy by electrocardiogram.
