A-Fib Rhythm Control Explained: Cardioversion, Medications, and Ablation — What Patients Need to Know

Managing atrial fibrillation (A-Fib) goes far beyond simply slowing the heart rate. In this episode of EP-EDGE Heart Talk, Dr. Niraj Sharma—cardiologist and cardiac electrophysiologist—breaks down everything patients and caregivers need to understand about restoring normal rhythm, improving symptoms, and protecting long-term heart health.

Whether you’ve been recently diagnosed with A-Fib, are living with persistent or long-standing persistent A-Fib, or are exploring treatment options for a loved one, this episode guides you step-by-step through the entire rhythm control journey.

In This Episode You Will Learn:

✔ What Rhythm Control Really Means

• How rhythm control differs in paroxysmal A-Fib vs. persistent A-Fib
• Why restoring sinus rhythm often improves energy, breathing, and overall well-being
• When rhythm control is recommended based on symptoms

✔ Cardioversion: What to Expect

• Why cardioversion is essential for persistent and long-standing persistent A-Fib
• How the procedure is done safely in the hospital
• What patients feel during (and after) the procedure
• Rare but possible complications like mild skin irritation

✔ Antiarrhythmic Medications: Pros, Cons, and Required Monitoring

• Amiodarone: effectiveness, thyroid/lung/liver risks, and need for labs, X-rays, and eye exams
• Sotalol: who it’s for, QT monitoring, kidney checks, and required echocardiogram
• Flecainide & Propafenone: highly effective—but only for patients with no coronary disease, no blockages, and no stents; echo, stress test, and labs required before starting
• Dofetilide: safe for heart failure patients but requires hospital initiation

✔ A-Fib Ablation: The Modern Path to Restoring Rhythm

• What to expect during an ablation under general anesthesia
• How 3D mapping and electrical signals guide precision treatment
• Differences between RF ablation, cryoballoon ablation, and the newest technology—Pulse Field Ablation (PFA)
• Success rates for paroxysmal, persistent, and long-standing persistent A-Fib

✔ Post-Ablation Recovery and Monitoring

• What symptoms are normal in the early weeks
• How we track recurrence using ECGs, Holters, event monitors, loop recorders
• Why smartwatches are now essential tools for long-term rhythm tracking

Who This Episode Is For

• Patients recently diagnosed with A-Fib
• Individuals with persistent or long-standing persistent A-Fib
• Anyone considering cardioversion, antiarrhythmic medications, or A-Fib ablation
• Caregivers supporting family members with atrial fibrillation
• Patients confused about rhythm control vs. rate control
• Anyone seeking clear, simple explanations from a heart rhythm specialist

Why You Should Listen

A-Fib can be silent, subtle, or severely symptomatic — and the right rhythm control strategy can dramatically improve quality of life.
Dr. Sharma provides a compassionate, comprehensive, and easy-to-understand roadmap that helps patients make informed decisions and take control of their heart health.
