[Echocardiographic study of left ventricular function in 2 different procedures].
Four patients on regular dialysis were studied by echocardiographic method during ultrafiltration sequential dialysis performed according to two different protocols: procedure 1: ultrafiltration alone (1 hour) followed by diffusive dialysis (3 hours); procedure 2: dialysis (3 hours) followed by ultrafiltration alone (1 hour). Blood pressure, heart rate, cardiac output, stroke volume, systolic and diastolic dimension of the left ventricle, systolic and diastolic volumes of the left ventricle, ejection fraction, shortening fraction and total peripheral vascular resistance index were measured. During ultrafiltration there is an increase of the total peripheral vascular resistance index. Myocardial contractility improves only during dialysis. Physiographic and therapeutic implications are discussed.
