An echocardiographic study of right ventricular myocardial contractility in 123 patients with chronic obstructive bronchitis (COB) confirmed the suggestion that in COB patients symptoms of right ventricular failure (cyanosis, acrocyanosis, crural edema, dilated liver) may have extracardiac origin. In echocardiographic diagnosis of right ventricular failure one should measure the speed of the anterior wall movements in the systole, diastole and ejection fraction.
一项针对123例慢性阻塞性支气管炎（COB）患者右心室心肌收缩力的超声心动图研究证实了以下观点：在COB患者中，右心室衰竭的症状（发绀、肢端发绀、下肢水肿、肝脏肿大）可能源于心外因素。在超声心动图诊断右心室衰竭时，应测量前壁在收缩期、舒张期的运动速度以及射血分数。
