动态心电图对无症状性心肌缺血的诊断价值
|
摘要
目的探讨动态心电图对无症状性心肌缺血的诊断价值。方法选取150例诊断为冠心病患者为研究对象,进行24 h动态心电图监测。结果 150例患者监测出心肌缺血发作共1420阵次,其中128例出现980阵次无症状性心肌缺血,平均每例发作(7.66±4.23)阵次,每次发作平均持续时间为(11.2±3.5)min。无症状性心肌缺血白天发作频率为夜间的1.92倍(645阵次vs 335阵次),且发作时心率较发作前明显上升,差异有统计学意义[(89.4±8.9)/min vs(72.8±8.4)/min,P<0.05]。结论动态心电图诊断无症状性心肌缺血的敏感性和准确性高,对于防治冠心病有重要临床意义。
Objective To study the clinical value of dynamic dectrocardiogram in detecting silent myocardial ischemia(SMI).Methods One hundred and fifty patients with coronary heart disease were detected by dynamic electrocardiogram for 24 hours.Results A total of 1420 times of SMI were detected in 150 patients,including 128 cases with 980 times of SMI.For every patient the SMI was(7.66 ±4.23)times and the length of attack time was(11.2 ±3.5)min.The seizure frequency in the daytime was 1.92 time of the nighttime(645 vs 335).The heart rate rose obviously when the SMI occured[(89.4±8.9) /min vs(72.8±8.4) /min,P<0.05].Conclusion The dynamic dectrocardiogram in detecting SMI has many advantages,such as high sensitivity and high accuracy,and it is significant for the prevention of SMI.
