运动试验观察指标R波振幅改变的分析及其机制探讨

本文通过对31例冠心病患者,21例心肌梗塞患者及30例正常对照者的运动试验R波振幅改变及其与心脏泵血功能,心输出量储备之间的关系进行对照分析,提示:1.△R波阳性作为诊断冠心病的一项参考指标具有应用价值。2.R波振幅的改变与心输出量及心脏的泵血功能,尤其是肺动脉楔压之间无明显关系。3.E系统可安全、简便地测定心储备力及心脏的泵血功能。对疗效评价和预后估测及对心电图运动试验多项参考标准产生机制的研究都具有重要的应用价值,值得推广使用。

ANALYSIS AND MECHANISM STUDY ON AMPLITUDE VARIATION OF AN OBSERVATION INDICATION OF EXERCISE TEST R WAVE

some examples of comparison analysis between R wave amplitude variations of exercise tests and heart pumping function, cardiac output reserve adopted from 31 cases of patient with coronary heart disease 21 cases of patient with myocardial infarction and 30 cases of normal persons were conducted in the paper, these results indicate that: 1. As a reference criteriom of diagnosis of coronary heart diserse, positive AR has applicable value. 2. The variation of R wave amplitude has little relation with cardiac output, heart pumping function, especially with pulmonary wedge pressure. 3. Cardiac reserve and heart pumping function can be easily and safely measured by system E. The study is of important applicable value for investigating curative effect , prediction of prognosis and the producing principles of some reference standards for electrocardiogram of exercise test. The result of the study are worthy for wide application.
