摘要
为探讨心电图运动试验心率恢复环评估冠状动脉病变的价值,分析74例患者(冠心病患者36例)的选择性冠状动脉造影及踏板运动试验资料。结果:(1)心率恢复环可分为A、B、C、D四种类型,其中A、B二型为异常;(2)心率恢复环诊断冠状动脉病变的敏感性、特异性和阳性预测价值分别为83.3％、81.6％和81.1％,与ST段压低标准无差异。(3)心率恢复环形态与冠状动脉病变支数相关性良好(P<0.001)。认为心率恢复环对诊断冠状动脉病变、特别是评判冠状动脉病变严重度有一定的实用价值。
In order to study value of heart rate-recovery loop during treadmill exercise test in diagnosis of coronary artery disease, data of coronary angiogram and exercise electocardiogram of 74 patients (36 cases with coronary artery disease) were analysed. Results: (1) Heart rate-recovery loop might be classified into four types: type A, type B, type C and type D. Type A and type B menifested abnormality. (2) Sensitivity, specificity and positive predictability to detect coronary artery disease were 83. 3%, 81. 6% and 81. 1% respectively , which were similar to those of standard ST segment depression criteria. (3) Types of heart rate-recovery loop were significantly correlated ( P < 0. 001) with number of diseased coronary arteries. It could be concluded that heart rate-recovery loop during treadmill exercise test is quite of value in diagnosis of coronary artery disease and particularly in assessing its severity.
