【摘要】 应用无创伤性技术测定108名正常人、27例心肌梗塞和62例冠心病人的主动舒张时间(TRT)和主动舒张时间指数(TRTⅠ),舒张期振幅时间指数(DATⅠ),RF相对振幅(F/H)和O-F间期(O-F)。结果显示心肌梗塞和冠心病组TRT和TRTⅠ分别比正常组延长和降低(P<0.01),其中以后者更为敏感。9例(33.33%)心肌梗塞和18例(29.03%)冠心病RF振幅降低至极限,以致F点消失,其余病例F/H和O-F低于和小于正常(P<0.01)。上述结果显示两组患者左室主动舒张功能和顺应性均有减退。因此,本研究为评价左室舒张功能提供了一个较实用方法。更多还原

【Abstract】 The total relaxation time (TRT), total relaxation time index (TRTI), diastolic amplitude time index (DATI), relative RF amplitude(F/H) and O-F interval (O-F) were performed by noninvasive technique in 108 normal subjects and 8.9 patients(myocardial infarction 27, coronary heart disease 62). The results showed that TRT and TRTI in patients with myocardial infarction and coronary heart disease were significantly longer and lower than that in normal subjecrs (p<0.01), and the TRTI was more sensitive than the TRT. The RF amplitude was extremely Ioweredln 9 patients with mybcardial infarction and in 18 with coronary heart disease, so that the point F was obscure. F/H and O-F in other patients were lower and shorter than those in normal subjets (p<0.01). Our results demonstrated that active relaxation and distensibility of the left ventricle were reduced in coronary diseases.更多还原
