Difference Between Chronotropic and Dromotropic

Chronotropic vs. Dromotropic

Chronotropic is a cardiac drug that affects heart rate. Dromotropic is a cardiac drug that affects conducting tissues of the heart.

Chronotropic vs. Dromotropic

Types of chronotropic drugs are the positive chronotropic drug and the negative chronotropic drug. Types of the dromotropic cardiac drug are the positive dromotropic drug and the negative dromotropic drug.

Chronotropic vs. Dromotropic

Chronotropic drugs are the ones that are utilized to deal with the heart rate of a patient. Dromotropic drugs are the ones that help in improvements in the state of electrical driving forces of the heart.

Chronotropic vs. Dromotropic

An example of the chronotropic cardiac drug is Dopamine whereas an example of the dromotropic cardiac drug is Phenytoin.

Chronotropicadjective

(physiology) Of, relating to, or affecting the rate of muscular contraction, especially of the heart.

Chronotropic vs. Dromotropic

There are many types of cardiac drugs, chronotropic and dromotropic are the types of cardiac medications. There are many cardiac problems, and each medicine is made for a specific kind of cardiac problem. The chronotropic cardiac drug is used to control heart rate whereas dromotropic is a cardiac drug works on conducting tissues of the heart. Likewise, there are types of chronotropic cardiac drugs that is a positive chronotropic cardiac drug that increases the heart rate whereas negative chronotropic drug slows the heart rate. If we talk about cardiac dromotropic medicines again, there are two types of cardiac dromotropic medicines, a positive dromotropic cardiac drug that increases the rate of conduction on the other hand negative dromotropic cardiac drug slows down the pace of conduction. The difference between these two drugs is by their function in our body.

What is Chronotropic?

Word Chronotropic means “heart rate of human”. Chronotropic is a cardiac drug that affects the heart rate of a human. Two types of chronotropic cardiac medication are positive chronotropic drug and negative chronotropic drug. The positive chronotropic drug increases the heart rate whereas negative chronotropic drug decreases the heart rate.

What is Dromotropic?

Dromotropic is a cardiac drug that affects conducting tissues of the heart. Dromotropic improves the condition of heart impulse. Dromo word means long distance. There are two types of dromotropic cardiac drug that are positive dromotropic cardiac drug and negative dromotropic cardiac drug. The positive dromotropic cardiac drug increases the electric impulse conduction whereas negative dromotropic cardiac drug decreases the electrical impulse conduction. An example of positive dromotropic is phenytoin, an example of negative dromotropic is verapamil. These drugs are given according to the condition of the patient.
