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.

ECG Blog #409 — Every-Other-Beat.

Ken Grauer, MD

Physiologically — the most commonly observed pattern of AFlutter, known as " Typical " AFlutter — produces 2:1 negative deflections seen in the inferior leads ( as seen in Figure-3 ) — as a result of CCW ( C ounter C lock W ise ) rotation of a fixed reentrant circuit around the tricuspid valve annulus and through the cavo-tricuspid isthmus.

Atrial dilatation in Atrial fibrillation : A query with multiple twists!

Dr. S. Venkatesan MD

In all probability, this dilation is a form of atrial tachycardia and atrial cardiomyopathy. However, underlying lesions such as hypertension, mitral valve disease, COPD, ASD, and TR greatly influence the degree of atrial enlargement. We know atrial flutters can be confined to one atrium.

Abstract 4142266: Long-term Outcomes and Predictors of Recurrence in Atrial Arrhythmia Ablations Post-Fontan Procedure: A Retrospective Analysis

Circulation

Introduction:Supraventricular tachycardia (SVT) is common and poorly tolerated in patients who have undergone Fontan procedure. Atrial Tachycardia (70%) and Typical Atrial Flutter (65%) were the most common SVTs ablated. Circulation, Volume 150, Issue Suppl_1 , Page A4142266-A4142266, November 12, 2024.
