drug used in ventricular arrhythmia:
- a) Phynetoin
- b) Quinidine
- c) Digoxin
- d) Procainamide***
- e) Verapamil.
The drug that is used in ventricular arrhythmia is (D) Procainamide.
Procainamide is an antiarrhythmic drug that is used to treat ventricular arrhythmias, such as ventricular tachycardia and ventricular fibrillation. It works by blocking sodium channels in the heart, which prevents the rapid firing of neurons that can lead to arrhythmias.
The other drugs listed in the answer choices are used to treat other types of heart conditions:
- Phenytoin is used to treat seizures.
- Quinidine is used to treat atrial fibrillation and atrial flutter.
- Digoxin is used to treat atrial fibrillation, atrial flutter, and heart failure.
- Verapamil is used to treat angina, high blood pressure, and supraventricular arrhythmias.
Procainamide is an effective drug for treating ventricular arrhythmias, but it can have serious side effects, such as agranulocytosis (a decrease in white blood cells) and lupus-like syndrome. Therefore, it is important to use procainamide under the close supervision of a doctor.
