The key difference between Chronotropic and Dromotropic is that chronotropic drugs affect the heart rate while dromotropic drugs affect the conduction velocity or the speed of the electrical impulse through the conducting tissues. Furthermore, chronotropic drugs affect the electrical conduction system of the heart and the nerves while the dromotropic drugs affect the atrioventricular node (AV node) conduction.
Diseases related to the heart and blood vessels are known as cardiovascular diseases. Heart attack, heart failure, arrhythmias, cardiomyopathy, angina, and stroke are some of them. Doctors prescribe cardiac drugs in order to prevent above diseases and keep your heart healthy. There are three main types of cardiac drugs in cardiac medication.
