曾有报道在日常生活中缺血发作呈昼夜2次节律构型,由此是否认为其与缺血阈限(以ST段低压1mm时的心率为计)的节律变化有关目前尚未清楚。方法与结果:为了评价日常生活中缺血阈限是否存在昼夜节律变化,以及与缺血发作的可能关系,作者对41例(男37,女4;均龄61±9岁)稳定型冠状动脉疾病者,但运动试验阳性,经持续不卧床ECG监护(AEM)证实,存在反复缺血发作者的总计1 371次缺血发作时的心率及其时段进行了分析。所有对象均连续接受AEM共7天。23例未服用任何治疗缺血
It has been reported in the daily life of ischemic attack was circadian rhythm configuration, whether it is considered with the ischemic threshold (ST-segment heart rate at 1mm when the meter) rhythm changes is not yet clear. Methods and Results: In order to evaluate the circadian rhythm of ischemic threshold in daily life and the possible relationship with ischemic attack, 41 patients (male 37, female 4; mean age 61 ± 9 years) with stable coronary artery Disease, but the motor test was positive. The heart rate and its duration during a total of 1 371 ischemic attacks in patients with recurrent ischemic attacks confirmed by continuous ambulatory ECG monitoring (AEM) were analyzed. All subjects received AEM for a total of 7 days. 23 patients did not take any treatment of ischemia
