运动负荷试验可辅助诊断心律失常,并会对原有心律失常产生影响。运动诱发的心律失常主要与年龄相关,常见的是房性早搏和室性早搏。冠心病者运动诱发的室性心律失常提示有较重的心肌缺血、室壁运动异常、心功能不全、冠状动脉严重病变及多支病变。其预后意义尚不一致。对冠心病者运动诱发的房性心律失常的预后评价是中性的。运动负荷试验还可诱发心肌病患者的心律失常。
Exercise stress test can help diagnose arrhythmia, and will have an impact on the original arrhythmia. Exercise-induced arrhythmias are mainly age-related and prevalent atrial premature beats and ventricular premature beats. Exercise-induced ventricular arrhythmias in patients with coronary heart disease suggest severe myocardial ischemia, abnormal wall motion, cardiac insufficiency, severe coronary artery disease, and multi-vessel disease. The prognostic significance is not the same. Prognosis of atrial arrhythmia induced by exercise-induced coronary heart disease is neutral. Exercise stress test can also induce arrhythmias in patients with cardiomyopathy.
