This part of the work contains the results of the comparative analysis of the graded physical loading (GFL) and Holter electrocardiogram monitoring (HEM) data. A silent false-negative depression of ST-segment during HEM was observed only in 2.5-8% of all investigated patients. It was established that the use of tests with GFL, HEM and hyperventilation allowed diagnosing more patients with silent myocardial ischemia as well as ST-segment dislocations have been seen in 97.2% cases. 9.1% of clinically healthy patients with risk factors and ST-segment depression were shown by means of myocardial scintigraphy with 201-T1 contrast. 50% of examined patients had silent ST-segment depression after psycho-emotional stress-tests. The comparison of the results of HEM and stress-tests showed that a ST-segment shift was more distinct in patients with episodes of symptomatic and silent myocardial ischemia than in those with silent myocardial ischemia. The article presents findings concerning the rate of ST-segment changes after the GEL test in recovery period. 5 types of ST-segment shift were distinguished.
该部分工作包含了分级体力负荷（GFL）与动态心电图监测（HEM）数据的对比分析结果。在所有接受调查的患者中，仅2.5 - 8%的患者在动态心电图监测期间出现了无症状性ST段压低假阴性情况。研究表明，采用分级体力负荷试验、动态心电图监测及过度换气试验能够诊断出更多无症状性心肌缺血患者，并且在97.2%的病例中观察到了ST段移位。通过201铊心肌显像显示，9.1%有危险因素且ST段压低的临床健康患者存在无症状性心肌缺血。50%的受检患者在心理 - 情绪应激试验后出现无症状性ST段压低。动态心电图监测结果与应激试验结果的比较表明，有症状性和无症状性心肌缺血发作的患者，其ST段移位比无症状性心肌缺血患者更为明显。本文介绍了恢复期GEL试验后ST段变化率的相关研究结果。区分出了5种ST段移位类型。
