无症状心肌缺血(附60例冠心病患者Holter监测)

Silent myocardial ischemia——Holter monitoring of 60 pateints with coronary heart disease

对60例冠心病患者(男53例、女7例,平均年龄58.1岁)进行动态心电图监测,并与常规12导联心电图对照。发现前者心肌缺血发作频率较高,二者之比为5.3:1;其中0.82患者心肌缺血发作时无任何症状,属无症状心肌缺血。并结合文献对其发生机理与临床意义简略讨论。

The 60 Pateints with coronary heart diseease (male 53 and female 7, mean age 58. 1 Years)were monitored Ambulatory electrocardiography (Holter monitoring)and were compared with routine 12 lead ECG. We discovered that in the myocardial ischemia rate detectable was higher,the ratio was 5. 3:1,of them,82% have no any symptoms,known silent myocardial ischemia (SMI). The mechanism and clinical significance of SMI were discussed.
