Inotropy, Lusitropy, Chronotropy, and Dromotropy

Lusitropy 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. This should not be confused, however, with catecholamine-induced … See more Increased catecholamine levels promote positive lusitropy, enabling the heart to relax more rapidly. This effect is mediated by the phosphorylation of phospholamban and troponin I via a cAMP-dependent pathway. … See more Relaxation of the heart is negatively impacted by the following factors: 1. Calcium overload – too much intracellular calcium 2. Reduced rate of calcium removal … See more WebLusitropy is myocardial relaxation.
