Catheter ablation of typical atrial flutter improves cardiac chamber size and function

Journal of Cardiovascular Electrophysiology

Abstract Introduction Cavo-tricuspid isthmus (CTI) dependent atrial flutter (AFL) is one of the most common atrial arrhythmias involving the right atrium (RA) for which radiofrequency catheter ablation has been widely used as a therapy of choice.

The positive F wave in lead V1 of typical atrial flutter is caused by activation of the right atrial appendage: Insight from mapping during entrainment from the right atrial appendage

Journal of Cardiovascular Electrophysiology

The positive F wave in lead V1 changed during entrainment from the right atrial appendage (RAA) during typical atrial flutter (AFL). Abstract Introduction Typical atrial flutter (AFL) is a macroreentrant tachycardia in which intracardiac conduction rotates counterclockwise around the tricuspid annulus.
