Final answer:
To treat A fib RVR, beta blockers and antiarrhythmic agents like amiodarone are used to control heart rate and rhythm.
Step-by-step explanation:
In the treatment of atrial fibrillation with rapid ventricular response (A fib RVR), several medications can be considered to control the heart rate and rhythm. Beta blockers, such as metoprolol or esmolol, are commonly used to slow down the heart rate.
Antiarrhythmic agents like amiodarone or procainamide may be administered to restore normal heart rhythm. Amiodarone, in particular, is effective for a variety of arrhythmias and is often the drug of choice despite potential long-term side effects. In addition to these, anticoagulants like warfarin (Coumadin) or newer agents.
Such as dabigatran (Pradaxa), rivaroxaban (Xarelto), or apixaban (Eliquis) are prescribed to prevent blood clots. For those with severe symptoms, urgent treatments such as cardioversion or defibrillation may be necessary. This involves a controlled electric shock to the heart to restore a normal rhythm.
