心缩间期(STI)是了解左室射血功能的一种无创性检查方法。为了评价STI对冠心病患者左室功能的准确性和敏感性,我们采用了握力负荷试验、吸烟试验和硝酸甘油含化试验。一、检查方法 STI测定用日本光电电子仪器厂生产的多种生理记录仪(RM6000),按通用方法,同时描记心电图,导联取标准导联Ⅱ或avF,以
Systolic interval (STI) is a noninvasive method of understanding left ventricular ejection function. To evaluate the accuracy and sensitivity of STI for left ventricular function in patients with coronary heart disease, we used a grip load test, a smoking test and a nitroglycerin-containing test. First, the inspection method STI determination with Japan’s optoelectronic electronic equipment factory production of a variety of physiological recorder (RM6000), according to a common method, while electrocardiogram, lead with standard lead Ⅱ or avF to
