心电图平板运动试验终止后影响心率恢复的因素分析

Influential factors for heart rate recovery after electrocardiogram treadmill exercise test

目的分析心电图平板运动试验后心率恢复的影响因素。方法 123例平板运动试验检查患者,按照试验后心率恢复情况分为正常组(67例)和异常组(56例),分析两组的临床资料及运动试验参数。结果异常组男性、超重、静息心率及合并糖尿病、冠心病、焦虑症比例明显高于正常组,而运动心率峰值低于正常组,差异均有统计学意义(P<0.01)。结论男性、超重、糖尿病、冠心病、焦虑症、静息心率增加、运动心率峰值降低是心电图平板运动试验后心率恢复的主要影响因素。

Objective To analyze the influential factors for heart rate （HR） recovery after electrocardiogram treadmill exercise test. Method Based on the HR recovery, 123 patients underwent treadmill exercise test were divided into normal （n=67） and abnormal （n=56） groups. Clinical data and treadmill exercise test parameters were analyzed in 2 groups. Results Compared with normal group, male, overweight, resting HR, and concomitant diabetes mellitus, coronary heart disease and anxiety were more common, while exercise HR peak was lower in abnormal group （P〈0.01）. Conclusion Male, overweight, diabetes mellitus, coronary heart disease, anxiety, incremental resting HR, and decreased exercise HR peak are the main influencing factors for HR recovery after treadmill exercise test.
