The heart failure may not be of any kind of disease but can be of any clinical syndrome that is caused by different types of cardiac dysfunction. The heart failure is termed as a failure of the heart to meet the demands of the body. Many different kinds of stimuli like hypertension, obesity, smoking, myocardial infarction, coronary artery disease, atrial fibrillation, and hypervolemia can trigger heart failure. Inotropic drugs, positive and negative chronotropic drugs, and dromotropic drugs are four classes of drug used to treat a heart failure.
Expert Solution & Answer
Explanation of Solution
Inotropic drugs: The positive inotropic drugs help to increase myocardial contraction force, while the negative inotropic drugs work in opposite of positive inotropic drugs like reduction in the contraction force.
Chronotropic drugs: The positive chronotropic drugs help to increase the heart rate, while negative chronotropic drugs help for decreasing the heart rate.
Dromotropic drugs: The positive dromotropic drugs help to increase the electrical conduction of the heart, while the negative will decrease the electrical conduction of the heart.
Conclusion
The differences between inotropic, chronotropic, and dromotropic drugs are discussed.
