Effects of chronic right ventricular volume and pressure loading on left ventricular performance.
The effects of chronic right ventricular (RV) distension on left ventricular (LV) funiction were assessed in dogs 3 weeks after pressure and volume loading of the RV lhad been produced by the emplacement of a constricting band around the pulmonary artery and the creation of tricuspid insufficiency. This resulted in ascites, RV hypertrophy and dilatation, an increase in RV end-diastolic pressure...

متن کاملEffect of right ventricular pressure on the end-diastolic left ventricular pressure-volume relationship before and after chronic right ventricular pressure overload in dogs without pericardia.
We studied the effect of chronic right ventricular pressure overload on diastolic ventricular interdependence in dogs without pericardia, instrumented to measure left ventricular pressure, right ventricular pressure, and 3 left ventricular dimensions. We studied 12 dogs before (control) and nine dogs after 6 weeks of pulmonary artery constriction producing systolic right ventricular pressure gr...
متن کاملPATHOPHYSIOLOGY AND NATURAL HISTORY VENTRICULAR PERFORMANCE Immediate effect of expiratory loading on left ventricular stroke volume
While the steady-state effects of positive pleural pressure on the circulation have been extensively studied, less is known about the immediate effects of positive intrathoracic pressure on cardiac dynamics. Therefore, we performed electrocardiographically gated radionuclide ventriculography with a respiratory gating technique in nine healthy subjects during quiet breathing and during expiratio...
متن کاملInfluence of Right Ventricular Hemodynamics on Left Ventricular Diastolic Pressure-Volume Relations in Man
To clarify the mechanism of displacement of the left ventricular diastolic pressure-volume function with alteration of loading conditions, the effects of nitroglycerin on pressure-volume relations in 13 patients were compared with those of amyl nitrite in 13 other patients during cardiac catheterization. After nitroglycerin, average systemic mean arterial pressure declined by 15.1 mm Hg (17%) a...
