平板运动试验诱发的心律失常分析

Analysis of arrhythmia induced by treadmill exercise test

目的 总结 12 7例运动试验病例伴发的心律失常资料 ,分析其临床特点。方法 12 7例病人依据冠状动脉造影结果分为冠心病组 6 6例 ,其中心绞痛 35例 ,心肌梗死 31例 ;非冠心病组 6 1例。应用Bruce方案 ,监测并分析心律失常类型。结果 心律失常发生率为 15 .7%。非冠心病组为 11.5 % ,冠心病组为 19.7% ,P >0 .0 5。心律失常以室性者最为多见 ,占 85 % ,房性心律失常占 15 %。心肌梗死的心律失常发生率为 2 9.0 % ,明显高于心绞痛病人11.4 % ,P <0 .0 5。且心律失常的发生可能与冠状动脉狭窄严重程度有关。结论 运动试验中发生心律失常比较常见 ,冠心病病人出现的心律失常可能与心肌缺血有关。

Objective The clinical features of arrhythmias happening in the treadmill exercise test (TET) of 127 patients were analyzed. Methods One hundred and twenty-seven patients were divided into two groups according to the results of coronary artery angiography (CAG). One was coronary heart disease (CHD) group with 66 cases, including 35 cases of angina pectoris(AP) and 31 cases of myocardial infarction (MI) ; the other group was non-CHD group with 61 cases. Bruce protocol was adopted and arrhythmia were observed and analyzed.Results The rate of arrhythmia induced by TET was 15.7%.It was 11.5% in non-CHD group and 19.7% in CHD group(P>0.05),respectively.Ventricular arrhythmia was most frequent. Its ratio was 85%, while 15% regarding atria ones. The rate in patients with MI was 29.0%,which was significantly higher than in patients with AP (11.4%) (P<0.05). The arrhythmias induced in TET perhaps had correlation with stenosing degree of coronary artery.Conclusion The arrhythmia induced in TET is common, it may be related to myocardial ischaemia in patients with CHD.
