摘要
本文通过对45例有一过性ST段压低的冠心病患者进行动态心电图观察,发现ST段压低时的室性心律失常与每日总缺血阵次及总缺血时间有密切关系。缺血期的心律失常发生率显著高于恢复期。ST段压低时的室性心律失常发生率在6～12时最高。
Forty-five patients with documented ischemic ST-segment depression were studied by 24 or 48 hour Holter monitoring. Ventrieular arrhythmias accompaying ST-segment depression were more frequently found in patients with more daily ischemie attacks and longer total ischemic time. The frequency of ventricular arrhythmias was greater at or before resolution of ST-egment depression(ischemic phase). The frequency of ischemic attacks accompanying ventricular arrhythmias showed circadian variation, which occurred more frequently hetween 6 AM and noon.
