摘要
本文通过对不稳定型心绞痛16例及稳定型劳累性心绞痛29例的24或48小时Holter观察,发现有91.6%和78.7%的SMI发生于一般活动、休息及睡眠中,有71.5%和65%的SMI在发作时不伴有明显的心率增加,提示大部分SMI的发生与原发性冠状动脉供血不足有关。
Sixteen patients with unstable angina(group A)and 29 patients with stable effort angina (group B) were examined by 1 or more 24-hour Holter recordings. In group A and B, 91.6% and 78.7% of silent myocardial ischemic episodes (SME) occured, while in the patients engaged in very low level activies 71.5% and 65% of SMI developed in the absence of significant increase in heart rate. The resules of this study revealed that the majority of SMI were probably related to transient decrease in coronary flow.
