目的:探讨运动试验及动态心电图对早复极综合征诊断意义。方法:对心电图呈ST段抬高,并排除器质性心脏病者行运动试验及动态心电图检查。结果:动态心电图较好的反映早复极综合征心电图特征,运动试验随心率增快,特征性ST段抬高可回落甚至降至等电位线。休息及运动恢复期原心电图特征恢复。结论:动态心电图及运动试验结合可提高早复极综合征诊断率,早复极综合征特征性ST段抬高有慢频率依赖性。
Objective: To investigate the significance of exercise test and ambulatory electrocardiogram in the diagnosis of early repolarization syndrome. Methods: ECG ST segment elevation, and exclude organic heart disease exercise test and Holter examination. Results: Holter better reflect the ECG characteristics of early repolarization syndrome, exercise test with heart rate increased, the characteristic ST segment elevation can be dropped or even down to the equipotential line. Rest and exercise recovery of the original ECG recovery. Conclusion: The combination of ambulatory electrocardiogram and exercise test can improve the diagnostic rate of early repolarization syndrome, and the characteristic ST segment elevation of early repolarization syndrome has a slow frequency dependence.
