Answer:
Positive inotropic effect means that it increases the contraction force of the heart, reducing the intracellular calcium level of the myocardium.
Step-by-step 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);
- conduction velocity in the atrioventricular node.
