对45例未接受抗心律失常治疗的各种类型心脏病患者进行等长握力训练和动态分级自行车训练时心律失常发生率的比较。房性心律失常在握手和自行车运动中同样常见，但室性心律失常在握手运动中更常见。在45名患者中，38%的患者在等长运动过程中出现室性心律失常，15%的患者发生室性心动过速。在动态运动期间，45名患者中有22%出现室性心律失常，其中2%发生室性心动过速。冠状动脉疾病和/或左心功能受抑的患者等长运动时室性心律失常的发生率是动态运动时的两倍。因此，等长运动试验比动态运动试验在揭示心脏病患者潜在性室性心律失常方面更有价值。
The incidence of arrhythmias during isometric sustained handgrip exercise and during dynamic graded bicycle exercise was compared in a group of 45 patients with various forms of heart disease on no antiarrhythmic therapy. Atrial arrhythmias were equally common during handgrip and bicycle exercise but ventricular arrhythmias were more frequent during handgrip exercise. Of the 45 patients, 38 per cent developed ventricular arrhythmias during isometric exercise, with ventricular tachycardia occurring in 15 per cent. During dynamic exercise 22 per cent of the 45 patients developed ventricular arrhythmias, with ventricular tachycardia occurring in 2 per cent. Patients with coronary artery disease and/or depressed left ventricular function developed twice the incidence of ventricular arrhythmias with isometric than with dynamic exercise. Thus, isometric exercise testing is of more value than dynamic exercise testing in unmasking latent ventricular arrhythmias in patients with heart disease.
