Atrioventricular reentrant tachycardia with a 2:1 right bundle branch block

Journal of Arrhythmia, 2012
The phenomenon of a 2:1 bundle branch block is reported during atrioventricular (AV) nodal reentrant tachycardia, sinus tachycardia, atrial fibrillation, and atrial flutter.

Atypical fetal junctional ectopic tachycardia: a case report and literature review

BMC Pregnancy and Childbirth, 2022
Background Junctional ectopic tachycardia (JET) is caused by ectopic rhythms, originating in the atrioventricular node, typically with heart rate between 200 and 250 bpm. Herein, we present a case of fetal JET with normal fetal heart rate and a review of

Simultaneous dual AV node antegrade conduction (2 for 1) and lower common pathway (2–1) block illustrate AVNRT physiology

Indian Pacing and Electrophysiology Journal, 2020
We report a rare case of spontaneous initiation of Atrioventricular nodal reentry tachycardia (AVNRT) via 2 for 1 phenomenon, into a 2:1 AV block due to lower common pathway block and finally transition to 1:1 tachycardia.

AV Nodal Reentrant Tachycardia in a Patient with Persistent Left Superior Vena Cava: Distinction between AV Nodal Versus Atrial Reentry

Journal of Arrhythmia, 2010
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 ...

Orthodromic atrioventricular reentrant tachycardia using a concealed isoproterenol-sensitive accessory pathway

Indian Pacing and Electrophysiology Journal, 2020
Accessory pathways (APs) represent the substrate for atrioventricular reentrant tachycardia. Catecholamine-sensitivity is an uncommon feature of APs and has been almost exclusively been described in APs with antegrade conduction. We present the rare case

Atrioventricular Node Reentrant Tachycardia (AVNRT) after mitral valvuloplasty during cardiac rehabilitation

Monaldi Archives for Chest Disease, 2015
We descrive a patient who presents palpitations during cardiac rehabilitation after mitral valvuloplasty. ECG showed regular narrow QRS tachycardia compatible with Atrioventricular Node Reentrant Tachycardia.

Transesophageal electrophysiology study in the diagnosis of dual atrioventricular nodal nonreentrant tachycardia

Annals of Noninvasive Electrocardiology, 2022
“Double fire” is generally characterized by 1:2 atrioventricular conduction of sinus beats traveling down fast and slow pathways that result in double ventricular response.

Dual AV Nodal Nonreentrant Tachycardia Resulting in Inappropriate ICD Therapy in a Patient with Cardiac Sarcoidosis

Indian Pacing and Electrophysiology Journal, 2014
Dual atrioventricular nodal nonreentrant tachycardia (DAVNNT) occurs due to concurrent antegrade conduction over fast and slow atrioventricular nodal pathways and is treated by slow pathway modification.

Atrioventricular Reciprocating Tachycardia Mediated by Twin Atrioventricular Nodes

JACC: Clinical Electrophysiology, 2016
A 21-year-old man with univentricular and uniatrial heart came for a third attempt at ablation of recurrent supraventricular tachycardia. He had undergone a previous cardiac surgery of a Blalock–Taussig shunt, and bidirectional Glenn, and the electrophysiological study revealed an ...
