应用心阻抗图对49例室性早搏患者按年龄分甲乙两组测定早搏前、中、后的每搏心排量。结果:两组的早搏前、早搏及早搏后心排量分别为85.4±20.6对62.4±22.4(P<0.001)、16.4±12.5对13.1±10.9(P<0.05)和108.4±26.6对85.1±31.4(P<0.01)。认为心阻抗图测定心排量研究早搏后强化作用,可用于估价不同年龄患者的心脏贮备功能。
Application of cardiac impedance map of 49 cases of premature ventricular contractions by age group A and B two groups measured premature beats before and after stroke stroke volume. Results: The cardiac output of premature beats, premature beats and premature beats were 85.4 ± 20.6 vs 62.4 ± 22.4 (P <0.001), 16.4 ± 12.5 vs 13.1 ± 10.9 (P <0.05) and 108.4 ± 26.6 vs 85.1 ± 31.4 (P <0.01). It is considered that the cardiac impedance map can be used to study the cardiac function after premature beat by measuring the cardiac output and can be used to estimate the heart reserve function in patients of different ages.
