心音图运动试验 (PCGET)是作者新近提出和进行的一项心肌收缩能力和心力储备的评估方法。为了验明 PCGET方法的实用价值 ,我们进行了该方法的敏感性和特异性的研究。对50个志愿者进行了 PCGET并按常规算式分析了该方法的敏感性和特异性。 PCGET的敏感性和特异性分别为 96 %和 10 0 %。反复的试验表明 ,PCGET是心力储备的无伤性、简便、代价低的量化测评方法
Phonocardiogram exercise test (PCGET) is a newly proposed and conducted a method of assessment of myocardial contractility and cardiac reserve. In order to verify the practical value of the PCGET method, we conducted a study of the sensitivity and specificity of this method. Fifty volunteers underwent PCGET and analyzed the sensitivity and specificity of the method according to a common formula. The sensitivity and specificity of PCGET were 96% and 100% respectively. Repeated trials have shown that PCGET is a nondestructive, simple, cost-effective quantitative assessment of cardiac reserve
