CIRCADIAN VARIATION OF TRANSIENT ISCHEMIA AND ISCHEMIC THRESHOLD IN FEMALE PTS

当心脏的血液供应因心脏的狭窄而受到限制时 冠状动脉，心肌缺血通常不会发生 伴随着胸痛。这些插曲可以通过连续的 使用动态心电图监护仪进行心电监护。虽然很多 有关男性脑缺血发生的信息可用 冠心病患者，女性患者是否有 与男性相比的差异还没有研究过。我们已经表演了 25例女性冠心病患者的动态心电图监测及分析 缺血发作的频度和时间分布 以及这些发作发生和比较的心率 她们对男性病人的攻击。脑缺血发作的昼夜节律变化 在早间涨潮的情况下，白天的高原和夜间的低谷是相似的 在女性患者中表现为男性。脑缺血发生时心率较低。 清晨的时间与一天中的其他时间相比。这是 同样类似于男性患者。

When blood supply to the heart is restricted because of narrowing of the coronary arteries, myocardial ischemia develops which is often not accompanied by chest pain. These episodes can be measured by continuous monitoring of the ECG by using the Holter monitor. Although much information is available about the occurrence of ischemia in male patients with coronary artery disease, whether female patients have differences compared to males has not been studied. We have performed Holter monitoring in 25 women with coronary artery disease and measured the frequency and distribution of the ischemic episodes according to time of day, and the heart rate at which these episodes occur and compared them against male patients. The circadian variation in ischemic episodes with a morning surge, a daytime plateau and a nighttime trough is similar in female patients as male. Ischemia develops at a lower heart rate in the early morning hours compared to other times of the day. This is again similar to male patients.
