Positive inotropic effect means that it increases the contraction force of the heart, reducing the intracellular calcium level of the myocardium.
Explanation:
Inotropism is a health science term to refer to the contraction capacity of the cardiac (myocardial) muscles. Inotropic action influences contractile force, velocity of myocardial pressure development and ejection velocity.
Negative inotropic effect means contraction force decreases or decreases cardiac output
Positive inotropic effect means that it increases the contraction force of the heart, reducing the intracellular calcium level of the myocardium.
Positive chronotropic action increases
heart rate -
tachycardia;
cardiac contraction force, both atrio and ventricles);
