Arrhythmia, Atrial Flutter and Electrophysiology

Functional block in the initiation and maintenance of common flutter: detailed electrophysiological study and electro-anatomical mapping

Frontiers in Cardiovascular Medicine

NOVEMBER 14, 2024

IntroductionThe precise pathophysiology of common atrial flutter remains imperfectly known. The direction of activation is therefore frequently counter-clockwise, and the arrhythmia stabilizes around the vena cavas and sinus venosus/crista terminalis region. Its rotation is limited by anatomical and functional boundaries.

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.

Although the QDOT MICRO™ Catheter was mainly designed for pulmonary vein isolation (PVI) its versatility to treat atrial fibrillation (AF) and other types of arrhythmias was recently evaluated by the FAST and FURIOUS study series and other studies and will be presented in this article.

Abstract Introduction Atrial fibrillation and atrial flutter originating from the donor s heart is a commonly reported complication post heart transplant. Case A 47-year-old male presented with atrial tachycardia 6 months post heart transplant. This arrhythmia was successfully terminated with radiofrequency ablation.

Unlike paroxysmal AF, which describes symptoms that last for seven days or fewer, persistent AF is a sustained arrhythmia that lasts for more than a week 1. Early treatment of persistent AF can reduce the risk of blood clots, stroke, and heart failure, and may prevent the disease from becoming permanent. The company now anticipates U.S.

Circulation: Arrhythmia and Electrophysiology, Ahead of Print. BACKGROUND:Inflammation may promote atrial fibrillation (AF) recurrence after catheter ablation. Colchicine did not prevent atrial arrhythmia recurrence at 2 weeks (31% versus 32%; hazard ratio [HR], 0.98 [95% CI, 0.59–1.61];P=0.92) 2.02];P=0.89).

The ECG was interpreted as showing atrial flutter with 2:1 conduction. The heart rate could be compatible with that of a 2:1 conducted atrial flutter. Also, lead I could give the initial impression of showing flutter waves. She presented to the emergency department after a couple of days of chest discomfort.

There is atrial activity before every QRS, but that activity has negative polarity, so it is not sinus rhythm. There are clearly no flutter waves, so it is not atrial flutter (a "macro-reentrant" atrial tachycardia) Is it AVNRT originating at the superior pole of the AV node, resulting in a retrograde P-wave before the QRS?
