对６０例经冠脉造影确诊的冠心病患者和６０例无心血管疾病（其申２４例冠脉造影正常）的对照组进行了体表电位标测（ＢＳＰＭ）研究。结果。心室除极（ＱＲＳ）电位平均逆转时间，冠心病组为３７．９７±１６．２８ｍｓ，对照。为４４．４９±１４．４１ｍｓ。两组比较差异非常显著（Ｐ＜０．０１）．电位“早期逆转”的发生率对照组为８．３％冠心病组为６３．３％，其中冠脉左前降支（ＬＡＤ）单支或含ＬＡＤ的多支血管狭窄组，电位早期逆转的发生率较高，且随冠脉病变评分的升高而升高。其诊断冠心病的敏感度为６３．３％，特异度为９１．７％。准确度为７７．５％以上结果提示；体表电位ＱＲＳ标测可用于检测冠心病慢性心肌缺血所致的心室除极电位异常，且有较高的特异度，但其检测的敏感度中等．建议临床应用时，最好采用ＱＲＳ和ＳＴ－Ｔ联合标测。以提高对冠心病的诊断价值。
Body surface potential measurements (BSPM) were performed in 60 patients with coronary artery disease confirmed by coronary angiography and 60 controls without cardiovascular disease (24 patients with normal coronary angiography). result. Ventricular depolarization (QRS) potential average reversal time, coronary heart disease group was 37.97 ± 16.28ms, control. 44.49 ± 14.41 ms. The difference between the two groups was significant (P <0.01). The incidence of “early reversal” of the potential in the control group was 63.3% in the 8.3% CHD group, in which coronary artery left anterior descending (LAD) mononuclear or multi-vessel stenosis group with LAD occurred and early reversal of electric potential occurred The rate was higher and increased with the increase of coronary artery disease score. The diagnosis of coronary heart disease was 63.3% sensitivity and specificity of 91.7%. Accuracy of 77.5% or more The results suggest that; body surface potential QRS mapping can be used to detect coronary heart disease induced by chronic myocardial ischemia ventricular depolarization potential abnormalities, and has a high specificity, but its detection sensitivity moderate . Recommended clinical application, the best combination of QRS and ST-T mapping. To improve the diagnostic value of coronary heart disease.
