What are Antiarrhythmics (Heart Rhythm)?

Antiarrhythmics are medications used to treat irregular heartbeats (arrhythmias) by restoring normal heart rhythm and improving heart function. These drugs play a crucial role in managing conditions like atrial fibrillation, tachycardia, and other rhythm disorders. Understanding how antiarrhythmics work can help you take control of your heart health.

How do Antiarrhythmics (Heart Rhythm) work?

Antiarrhythmics work by affecting the electrical signals that control your heart's rhythm. They can slow down an overactive heart, stabilize erratic beats, or restore a normal rhythm by blocking specific ion channels or modulating heart activity. This helps your heart pump more efficiently and reduces symptoms like dizziness, fatigue, or palpitations.

What conditions do Antiarrhythmics (Heart Rhythm) treat?

Antiarrhythmics are commonly prescribed to treat:

Atrial fibrillation (AFib)
Ventricular tachycardia
Supraventricular tachycardia (SVT)
Premature ventricular contractions (PVCs)
Arrhythmias following heart attacks or surgeries

These medications provide critical support for maintaining heart health and preventing complications like stroke or heart failure.

Common medications in Antiarrhythmics (Heart Rhythm)s

Popular antiarrhythmic medications include:

Amiodarone (Cordarone, Pacerone): Treats a wide range of arrhythmias
Sotalol (Betapace): Effective for ventricular and atrial arrhythmias
Flecainide (Tambocor): Stabilizes the heart's rhythm in atrial fibrillation or flutter
Dofetilide (Tikosyn): Used for persistent AFib and atrial flutter
