Answer 1

The most common antidysrhythmia drugs used to convert to and maintain sinus rhythm include beta-blockers, calcium channel blockers, and digoxin.

Step-by-step explanation:

The most common antidysrhythmia drugs used for conversion to and maintenance of sinus rhythm include:

1. Beta-blockers: These drugs block the β-receptors associated with vasoconstriction and cardioacceleration, improving cardiac function. Examples include metoprolol and propanolol.
2. Calcium channel blockers: These drugs decrease the strength of contraction and SV. Examples include amlodipine, diltiazem, and verapamil.
3. Digoxin: This drug is used to control the rate and rhythm of the heart in certain types of arrhythmias.
