Premature Beats With QRS Morphology Identical to Sinus Rhythm: What Is the Mechanism
This case illustrates a rare presentation of premature junctional contractions arising from the atrioventricular nodal region, particularly the slow pathway, mediated by non‐sustained reentrant activity. This mechanism does not result in sustained tachycardia but instead produces isolated echo beats.

As different from radiofrequency current energy, cryofreezing energy is able to provide reversible effects on cardiac tissue, called “cryomapping,” which enables us to predict the effects of a subsequent application of ablative energy.

Coronary sinus diameter by echocardiography to differentiate atrioventricular nodal reentrant tachycardia from atrioventricular reentrant tachycardia [PDF]
Background: Coronary sinus (CS) has been shown to be larger in patients with atrioventricular nodal reentrant tachycardia (AVNRT). We sought to determine if echocardiographically measured CS diameter can help identify the mechanism of tachycardia in ...

In 125 consecutive pediatric and young adult patients (age ≤ 21 years), zero‐fluoroscopy radiofrequency slow‐pathway modification for AVNRT—guided entirely by CARTO 3D electroanatomic mapping—achieved 100% acute success, zero recurrences at 36‐month follow‐up, and zero major complications, supporting fluoroless RF ablation as a durable first‐line ...

Among patients with recurrent unexplained syncope and no prior AF, LV diastolic dysfunction quantified by the HFA‐PEFF score predicts sick sinus syndrome and atrial fibrillation. ABSTRACT Background Atrial fibrillation (AF) and sick sinus syndrome (SSS) frequently coexist and may share common atrial structural and electrophysiological remodeling ...

Catecholamine-dependent atrioventricular nodal reentrant tachycardia.
An unusual case of atrioventricular nodal reentrant tachycardia precipitated by ethanol ingestion is presented. Programmed atrial and ventricular stimulation failed to induce the tachycardia during control conditions or after atropine administration ...

ABSTRACT Late‐onset third‐degree atrioventricular (AV) block is a rare life‐threatening complication that may develop years after surgical correction of Ebstein anomaly. Effective management depends on routine cardiac monitoring and timely intervention with an epicardial permanent pacemaker.

Third‐degree AV block sensitive to prednisolone 72 hours post AVNRT ablation
Key Clinical Message A patient developed a transient first‐degree AV block during a radiofrequency ablation of an atrioventricular nodal reentrant tachycardia. Three days later the patient presented with a third‐degree AV block.

A 75-year-old male presented with palpitation on exertion. He suffered from frequent tachycardia attacks. His 12-leads electrocardiogram showed irregular cycle lengths (400–550 ms) of tachycardia with occasional 2:1 atrioventricular conduction (thus AV ...
