Changes in ST-T complex were studied using Holter electrocardiographic monitoring in 83 male patients with stable angina of effort. Episodes of transitory ST displacement were detected in 74.8% of patients. Of the recorded 886 ST displacement episodes, ST depression was seen in 35.9% of cases, with accompanying anginal pain in 88.4% of those. ST elevation was seen in 64.1% of cases, but anginal pain only accompanied a more than 2 mm elevation in 3.2% of those, while 96.8% of 1-2 mm elevations were asymptomatic. Total duration of ST depression was found to be an objective criterion for the assessment of the severity of stable angina of effort, amounting to less than 1% of the day in patients referred to functional class (FC) 1, 1-4% in FC 2, 5-10% in FC 3 and more than 10% in FC 4.
采用动态心电图监测对83例稳定型劳力性心绞痛男性患者的ST-T复合波变化进行了研究。74.8%的患者检测到短暂性ST段移位发作。在记录的886次ST段移位发作中，35.9%的病例出现ST段压低，其中88.4%伴有心绞痛。64.1%的病例出现ST段抬高，但只有3.2%的ST段抬高超过2mm时伴有心绞痛，而96.8%的1-2mm抬高无症状。ST段压低的总时长被发现是评估稳定型劳力性心绞痛严重程度的客观标准，在功能分级（FC）1级的患者中占比不到一天的1%，FC2级为1-4%，FC3级为5-10%，FC4级超过10%。
