Flecainide: Electrophysiological properties, clinical indications, and practical aspects

Area of Science:

• Cardiology
• Pharmacology

Background:

• Flecainide has been a key anti-arrhythmic drug for 35 years.
• Initially for ventricular arrhythmias, it's now central to atrial fibrillation management in specific patients.

Purpose of the Study:

• To provide a comprehensive review of flecainide's anti-arrhythmic effects.
• To detail its electrophysiological properties, clinical applications, and safety profile.

Main Methods:

• Literature review of flecainide's properties and clinical use.
• Analysis of electrophysiological data and clinical trial outcomes.

Main Results:

• Flecainide is effective for atrial fibrillation, supraventricular tachyarrhythmias, and ventricular pre-excitation.
• New formulations improve patient compliance and clinical utility.
• Despite historical safety concerns (Cardiac Arrhythmia Suppression Trial), flecainide is now considered safe for many indications.

Conclusions:

• Flecainide remains a vital tool in managing cardiac arrhythmias.
• Understanding its properties, uses, and contraindications is crucial for effective clinical practice.
