False. alcohol is a depressant.
Answer:
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);
- conduction velocity in the atrioventricular node.

Moreover, the effects of stimulant includes
the brain processes of sensory information throughout the body, muscle movement
and locomotion, bodily functions, thoughts and feelings, perception and moods and
thus, create disturbance over the controls of all behavior.</span></span>
