【摘要】 采用无创伤性阻抗微分图法测定32例肥胖患者的肺动脉楔压（Q-S₁/A₂-O）、每搏排血量（SV）、心输出量（CO）、心脏指数（CI）、心搏指数（SI）、快速射血期（BZ）、左心功能指数（QZ）等心功能指数,与正常人对照分析,肥胖者Q-S₁/A₂-O升高,BZ,QZ延长,CI、SI降低,差异有显著性（P<0.01）,其在测定肥胖者心功能上具有重要意义。该种方法不受肥胖影响,比超声法优越。并叙述了肥胖性心肌病的特点、病理、生理、临床表现,指出了与肺心病、冠心病的鉴别要点。更多还原

【Abstract】 This paper described the pathojogical, physiological and clinical features of obese cardiomypathy and pointed out the highlights for differentiating it from cor pulmonale and coronary heart disease. The author assesssed a series of cardiac indexes in 32 simple obese patients and 30 healthy normal subjects. Noninvasive methods, including impedance cardiographic tracing ECG and phonocardiography, were employed to determine the pulmonary wedge pressure (Q-S1/A2-0 ) stroke vulume (SV), cardiac output (CO), cardiac index (CI), stroke index (SI), rapid ejection time (BN)and left ventricular performance index (QZ)。 Comparison revealed singnificant differences between the obese and the normal in that the obese had their Q-S1/A2-O elevated, BZ and QZ prolonged, and CI and SI decreased (P<0.01). These findings areof importanae in evaluating the cardiac functions of the obese, Themethods employed have proved to be superior to echocardiography, for the latter is usually influenced by obesity and produces unsatisfactory nonconclusive results.更多还原
