65例阵发性胸痛患者动态心电图分析

Holter analysis in 65 patients with paroxysmal chest pain

目的:探讨阵发性胸痛患者的24小时动态心电图变化情况。方法:对65例阵发性胸痛患者进行24小时心电图连续监测,并详细记录监测时间内的生活及活动情况。结果:65例患者休息、活动时均有ST段压低,但以活动时发作较多,ST段压低时快频依赖者占64.6%,发生心律失常占70.8%,其中室上性早搏和室性早搏占92.6%。结论:动态心电图是诊断短暂或持续心肌缺血的可靠指征。

Objective： To analyze the ECG deviations according to 24-hour Holter monitoring of patients with paroxysmal chest pain. Methods： 24-hour Holter monitoring was examined in 65 patients with paroxysmal chest pain, meanwhile daily activities and exercises were also recorded. Results： ST segment depressions were presented in all cases no matter the patient was at quiet state or motion state, more frequently under the latter circumstance. 64.6% patients had coexistence of ST segment depression and tachycardia. Arrhythmia was presented in 70.8% cases, of which 92.6% were supraventricular premature beats and ventricular premature beats. Conclu- sion： Holter is a reliable method for diagnosing both transient and continuous myocardial ischemia.
