本文通过宽频带心电图、普通心电图和核素心脏断层显影(SPECT)三者对正常人和冠心病患者进行对照检测。发现心梗组经过三种检查,阳性率均达100%而无差异;对心绞痛和慢冠组检查结果表明宽频带心电图和 SPECT 的阳性率均明显高达100%,普通心电图仅为50%;对慢冠组则 SPECT 法阳性率为92.85%,宽频带心电图为88.09%,普通心电图仅达47.62%。经卡方测验宽频带心电图和普通心电图之间差别非常明显,宽频带心电图和 SPECT 的差别则不明显。
In this paper, a wide range of ECG, ECG and radionuclide heart imaging (SPECT) of three normal controls and coronary heart disease patients were detected. The results of three tests showed that the positive rate of 100% in the MI group was no difference. The results of angina pectoris and slow coronet group showed that the positive rates of wide-band electrocardiogram and SPECT were all as high as 100%, while the common ECG was only 50% In the slow crown group, the SPECT positive rate was 92.85%, the wideband electrocardiogram was 88.09%, and the common electrocardiogram was only 47.62%. The chi-square test between the wideband ECG and ordinary ECG is very clear difference between wideband electrocardiogram and SPECT is not obvious.
