Are Antiarrhythmic Drugs the Answer to Atrial Fibrillation?

What Are Antiarrhythmic Drugs?

Antiarrhythmic drugs are medications used to restore a normal heart rhythm and prevent the recurrence of atrial fibrillation. These drugs work by modifying the electrical signals in the heart to maintain a steady beat. Common examples include amiodarone and propafenone.

Effectiveness and Side Effects

While antiarrhythmic drugs can be effective, they come with potential side effects such as dizziness, fatigue, and, in some cases, more serious heart issues. Success rates vary, with about 35 to 60 percent of patients experiencing AF recurrence within a year. Therefore, ongoing monitoring and adjustments in therapy may be necessary.

Who Should Consider These Drugs?

Antiarrhythmic drugs are typically prescribed for patients with symptomatic AF who are younger than 80 years or have high cardiovascular risks. They are not recommended for everyone due to the possibility of side effects, particularly in older adults or those with specific health conditions.
