【摘要】 目的探讨平板运动试验对早复极综合征的诊断意义。方法22例心电图呈早复极改变患者,随访9～34个月,每6个月复查心电图一次,19例在随访期接受次极量活动平板运动试验,每2min记录一次心电图,休息20min后再次记录心电图。结果随访期间,22例患者中19例早复极综合征的心电图特征无明显改变,另3例ST-T发生了明显变化。运动试验中随心率增快,特征性的ST段抬高可逐渐回落甚至降至基线水平。休息后,19例患者原心电图特征均恢复。结论早复极综合征的特征性ST段抬高具有慢频率依赖性,平板运动试验有重要诊断价值。更多还原

【Abstract】 Objective To explore the identification of early repolarization syndrome (ERS) and its clinical significance by exercise electrocardiogram test. Methods 22 ERS cases were followed for 9 to 34 months,and electrocardiogram (ECG) was recorded every 6 months. 19 subjects were selected for treadmill exercise test. ECGs were recorded every 2 minutes and 20 minutes after rest. Results The characteristic ECG of ERS remained unchanged in 19 out of 22 cases during the 9 to 34 months follow-up. In the 19 subjects receiving exercise test,ST segment elevation lowered down in 8 (42%) and disappeared in 11 (58%) after the heart rate increased,and recovered slowly with the heart rate slow down. Conclusions The characteristic ECG change of ERS is slow rate dependent, treadmill stress test is helpful in scanning and diagnosis. [更多还原
