摘　　要：目的　观察踏车运动试验的心率应答反应特点 ,运动前后心脏做功指数的变化。方法　抽取踏车运动试验阳性且临床诊断为冠心病的患者 118例。对照组为运动试验阴性 10 7例。进行踏车运动试验检查。结果　表明冠心病患者男性 74% (49/ 6 6 ) ,女性 73% (38/ 5 2 )达到了目的目标心率 ,而且实际增加的心率较阴性组为少 ,两组有非常显著差异 (P<0 .0 1) ,运动后两组的收缩压和做功指数 (心率×收缩压 )有显著性差异 (P<0 .0 5 )。结论　冠心病患者心脏做功指数降低除与心率减慢直接相关外与收缩压不升或略升高有直接相关。Objective To cvaluate the diagnostic charaeterstios of change at the rhythmia and DI for coronary artery disease.Methods The chang at the rhythmia and DI was measured in 118 cases with coronary artery disease and 107 cases nomal controlled groups by exercise trendmill test.Result The results show that number of aim rhythmia who can reaehed standard were male 74%(49/66) and female 73(38/52)with coronary artery disease were lower compared with those of the nomal controlled groups( P <0.01).The two groups have very large different at systolic pressure and DI after treadmill exerise test( P <0.01).Conclusion Lower DI of coronary artery disease have relationship direetly with lower rhythmia and have relationship direetly with no increased or unsignificantly increased of systolicp pressure.
