Tachycardia cycle length alternans caused by alternate conduction velocity on the slow conduction zone in a postoperative scar‐related atrial tachycardia
Sign Up to like & getrecommendations! Published in 2019 at "Journal of Arrhythmia"
DOI: 10.1002/joa3.12177
Abstract: The underlying mechanism for stable beat‐to‐beat cycle length variability (CL alternans) in scar‐related atrial tachycardia (AT) had not been elucidated clearly. We described a case with postoperative dual‐loop reentrant AT in right atrium. When the… read more here.

DOI: 10.1002/joa3.12313
Abstract: A 45‐year‐old man with paroxysmal atrial fibrillation (PAF) was admitted to our hospital for hot balloon ablation. At admission, atrial tachycardia (AT) was observed. Activation map showed focal atrial tachycardia originating from the posterior wall… read more here.

Atrial tachycardia misinterpreted as ventricular high‐rate event in a patient with the sick sinus disease and a DDD pacemaker

DOI: 10.1002/joa3.12497
Abstract: The device misinterpreted atrial high‐rate episode (AHRE) as ventricular high‐rate episode (VHRE), since consecutive atrial beats fell in the postventricular atrial blanking (PVAB) period. This resulted in the failure of auto mode switch (AMS). This… read more here.

DOI: 10.1002/joa3.12702
Abstract: Constant pacing (S1–S1: 520 ms) from the right atrial appendage (RAA) during reentrant atrial tachycardia originating from the atrioventricular node vicinity. RA‐FW 1–2 was constantly captured antidromically. However, the earliest atrial activation site (EAAS =… read more here.

DOI: 10.1016/j.hrcr.2017.10.010
Abstract: Introduction Ectopic atrial tachycardia occurs at a rate of 5%–20% among children with supraventricular tachycardia. Atrial appendages are the most frequent focus in children, differing from the situation in adults. However, ectopic atrial tachycardia originating… read more here.
