Ionotropic effect - Wikipedia

WebContractility, or inotropic state, is defined as the property of myocardial fibers that determines the extent of shortening independent of loading conditions. Compared with the control state, a positive inotropic intervention (e.g., epinephrine) increases myocardial fiber shortening and stroke volume at any given preload and afterload. WebLusitropy is the rate of myocardial relaxation. The increase in cytosolic calcium of cardiomyocytes via increased uptake leads to increased myocardial contractility (positive inotropic effect), but the myocardial relaxation, or lusitropy, decreases. block tronchado
