动态心电图表现对猝死患者的预测价值

摘要

目的探讨运动心电图表现对猝死患者的预测价值.方法 3600例健康男性进行标准化踏车运动试验.先描记卧位12导联心电图,测量基础血压与心率,然后进行加强双倍二级梯运动测验.运动后测即刻卧位血压与心率,并描记心电图,每导联描记5个P-QRS-T波.结果 受试者均为男性,平均随访时间(19±6)年,死亡(全死因)325例(9%),心脏病死亡144例(4%),其中45例为猝死患者,99例为非猝死患者.猝死患者运动试验期间最大平均心率(96±0.8)次/min,非猝死患者或生存者为(97±0.6)次/min.结论 运动试验过程中的心率变化模式与无症状健康男性猝死之间存在关联.%Objective To investigate the prediction value of electrocar dio graphic manifestations for sudden death. Methods 3600 healthy males, tiialed far standardized treadmill exercise. First supine 12-lead ECG tracings, and the measurement of basal blood pressure and heart rate were done,then strengthened double two ladder exercise tests were done. Supine blood pressure and heart rate were immediately measured after exercise, and electrocardiogram for live P-QRS-T wave per lead were traced. Results The subjects were male,the mean follow-up time weie( 19 ?6 )years, there were 325 cases of death( all causes,9% ), among which cardiac death were 144cases(4% ), including 45 of sudden death and 99 cases of non-sudden death. The average maximum heart rate were( 96 ?0. 8 )times/minin patients with sudden death during exercise test and patients of non-sudden death or survivor weie( 97 ?0. 6 )times/min. Conclusion The changes of heart rate during of exercise test is associated with asymptomatic healthy male death.
