摘　　要：目的　探讨运动试验诱发室性心动过速的临床意义。方法　对 76 6 4例运动试验病人中诱发室性心动过速 36例进行分析。结果　 76 6 4例运动试验病人有 36例发生室性心动过速 ,占 4 7‰ ,其中 ,心肌缺血阳性组 2 383例发生室性心动过速 17例 ,发生率为 7 1‰ ,阴性组 5 2 81例发生室性心动过速 19例 ,发生率为 3 6‰ ,两者差异有显著性(P <0 0 5 )。且阳性组发生的室性心动过速阵数多 ,形态多变。结论　运动试验中检出恶性心律失常与缺血有明显相关 ,且阳性组发生的室性心动过速阵数多 。Objective To evaluate the clinical significance of ventricular tachycardia evoked by exercise test. Methods To analyse the conditions of the 36 patients who had been evoked ventricular tachycardia during exercise test. Among 7 664 patients.Results There were 36(4 7‰) patients with ventricular tachycardia in total patients. There were 17(7 1‰) patients had ventricular tachycardia among 2 383 patients with myocardial ischemia, There were 19(3 6‰) patients had ventricular tachycardia among 5 281 patients had no myocadial ischemia, the probability of ventricular tachycardia between two groups was significantly difference ( P<0 05 ). We also found the ventricular tachycardia among the ischemia group were more variable form and frequent onsets in ECG. Conclusion There is correlation between the myocardial ischemia and malignant arrhythmia in the exercise test. And it would be cuing myocardial ischemia if the ventricular tachycardia are more variable forms and frequent onsets.
