【摘要】 侵入性与非侵入性心排血量测定研究分三组:1.应用热稀释法与阻抗法测定心排血量29例,呈低度相关,r=0.32。2.应用Fick法与阻抗法测定15例,是高度相关,r=0.77。3.正常对照组133名及甲亢组40例与冠心病组60例,阻抗法测定,其数值在正常对照组为5.43±1.99l/分,提示各年龄组间有显著差异(P<0.01)。甲亢组7.70±2.81l/分,冠心病组4.38±1.57l/分。初步认为阻抗法测定心排血量有定性价值。更多还原

【Abstract】 1. The cardiac output of 29 patients were measured by thermal dilution andimpedance cardiogram method. The correlation of these two methods revealed low,r=0.32. 2. 15 cases were measured by Fick and impedance cardiogram methods, theircorrelation revealed high, r=0.77. 3. The cardiac output of 133 normal persons and 100 patients (hyper thyroid-ism 40, coronary heart disease 60) were measured for comparison by impedancecardiogram method. The results are as follows: normal group… the mean cardiacoutput and its standard deviation = 5.43±1.99 litres/min. It suggested significantdifference in all differrent age groups (P<0.01). Hyperthyroidism group… themean cardiac output and its SD= 7.70±2.81 litres/min. Coronary heart diseasegroup… the mean cardiac output and its SD = 4.38±1.57 litres/min. Conclusion: Measurement of cardiac output by means of impedance cardiogrammethod is highly valuable in qualitative assessment but not quantitative inclinical use.更多还原
