对正常成人与高血压、冠心病、风心病及肺心病患者采用常规导联法与Nehb导联心电图作对比分析,认为:Nehb导联心电图作为对高血压、冠心病与风心病等的检查手段时,虽然目前尚无统一的诊断标准,但仍有较肯定的临床价值。关于D导联反映左室电压异常、心肌劳损或缺血性改变以及左房异常增大等方面,笔者从理论上作了试探性的分析、讨论,还有待今后进一步探讨与证实。A导联位置更近于室间隔部位,最好不以该导联反映的R波高电压作为左室电压异常的诊断指标。
For normal adults and patients with hypertension, coronary heart disease, rheumatic heart disease and pulmonary heart disease by conventional lead method and Nehb lead electrocardiogram for comparative analysis, that: Nehb lead ECG as a check on hypertension, coronary heart disease and rheumatic heart disease Although there is no uniform diagnostic criteria, but there is still more certain clinical value. On the D lead reflects abnormal left ventricular voltage, myocardial injury or ischemic changes and increased left atrial abnormalities, the author made a tentative analysis of the theory, discussion, to be further explored and confirmed in the future. A lead position closer to the septal site, it is best not to lead the R wave reflected high voltage as a diagnostic indicator of abnormal left ventricular voltage.
