The cardiointegram is a noninvasive technique for the analysis of the electrical signals of the heart obtained by a transformation of the voltage versus time format by a series of integrations. The stress thallium perfusion study is a widely used test for the detection of coronary artery disease. In order to evaluate the correlation between the resting cardiointegram and the stress thallium 201 perfusion study, 20 patients with normal resting electrocardiograms underwent stress thallium tests and resting cardiointegrams. The cardiointegram was determined on two resting complexes of leads I, II, V4, V5, and V6 and called abnormal if five of ten complexes deviated outside a normalized template. There was concordance of the cardiointegram and the thallium study in 16 of 20 patients (80%). The sensitivity for the detection of coronary artery disease was 71%, and the specificity was 80%. The overall accuracy was 74%. Thus in patients with normal electrocardiograms, the cardiointegram is a useful noninvasive test for the detection of coronary artery disease.
心脏积分图是一种非侵入性技术，用于分析通过一系列积分将电压与时间格式转换后获得的心脏电信号。应力铊灌注研究是一种广泛用于检测冠状动脉疾病的测试。为了评估静息心脏积分图与应力铊201灌注研究之间的相关性，对20例静息心电图正常的患者进行了应力铊测试和静息心脏积分图检查。在导联I、II、V4、V5和V6的两个静息复合波上测定心脏积分图，如果十个复合波中有五个偏离标准化模板，则称为异常。20例患者中有16例（80%）心脏积分图和铊研究结果一致。检测冠状动脉疾病的敏感性为71%，特异性为80%。总体准确率为74%。因此，对于心电图正常的患者，心脏积分图是一种用于检测冠状动脉疾病的有用的非侵入性测试。
