Explanation:
Detailed explanation-1: -Chronotropic drugs may change the heart rate and rhythm by affecting the electrical conduction system of the heart and the nerves that influence it, such as by changing the rhythm produced by the sinoatrial node. Positive chronotropes increase heart rate; negative chronotropes decrease heart rate.
Detailed explanation-2: -Positive chronotropes increase heart rate; however, negative chronotropes decrease heart rate. A dromotrope affects Atrioventricular node (AV node) conduction.
Detailed explanation-3: -Negative chronotropes–> Decrease heart rate. Positive chronotropes–> Increase heart rate.
