Multifocal Atrial Tachycardia (Chaotic Atrial Tachycardia) [PDF]
Circulation, 1970 Multifocal atrial tachycardia, also designated "chaotic atrial tachycardia," was identified in the records of 31 patients. It was particularly noted that the arrhythmia progressed to atrial fibrillation or flutter in 17 cases (55%). Unifocal or multifocal premature atrial contractions preceded the arrhythmia in 20 cases (64%).

Journal of International Medical Research, 2022 Ivabradine is an effective treatment for focal atrial tachycardia. However, it may also be effective for re-entrant atrial arrhythmia. An 85-year-old woman with a history of underlying ischaemic cardiomyopathy complained of worsening symptoms of heart ...

Arrhythmias Beyond Atrial Fibrillation Detection Using Smartwatches: A Systematic Review
Anatolian Journal of Cardiology, 2023 Background: Over the past few years, smartwatches have become increasingly popular in the monitoring of arrhythmias. Although the detection of atrial fibrillation with smartwatches has been the subject of various articles, there is no comprehensive ...

Change in VA interval by a single atrial premature depolarization - What is the mechanism?
Indian Pacing and Electrophysiology Journal, 2022 A long VA tachycardia during a typical atrioventricular nodal reentrant tachycardia (AVNRT) can be a concomitant atypical AVNRT, atrial tachycardia or rarely atrio-ventricular reentrant tachycardia (AVRT).

Rapid wide QRS tachycardia with an unknown cause
Annals of Noninvasive Electrocardiology, 2022 One‐to‐one atrioventricular conduction during atrial flutter is one of the most severe life‐threatening arrhythmias and is hemodynamically perilous. Rapid wide QRS tachycardia often not only occurs in patients with ventricular tachycardia but is also ...
