Focal Atrial Tachycardia [PDF]
Journal of Arrhythmia, 2006 AbstractOver the past decade most of the electrophysiologic mechanisms in patients with focal atrial tachycardias (ATs) have been well studied Recently advanced mapping systems have revealed the precise propagation and the relationship between non radial propagation pattern and substrate property of focal AT Non radial activation pattern of focal AT ...

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 ...

A Hidden Recess of Atrial Tachycardia [PDF]
Journal of Innovations in Cardiac Rhythm Management, 2021 We present a case of regular narrow complex tachycardia in a 59-year-old woman with frequent paroxysmal palpitations, a normal electrocardiogram (ECG) in sinus rhythm, and a structurally normal heart. During electrophysiology study, a long R-P tachycardia was present at baseline, with P-waves superimposed on the T-waves and appearing to be positive in ...

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).

Frontiers in Pediatrics, 2020 We report on a 12-month-old girl with an ectopic atrial tachycardia successfully treated with the combination of a beta blocking agent and Ivabradine that acts on cardiac pacemaker cells by selectively inhibiting the If channel.

Deglutition-Induced Atrial Tachycardia [PDF]
Cureus, 2021 While bradyarrhythmia is the most common arrhythmia during deglutition, tachycardias are considered to be a very rare condition with approximately 50 cases documented worldwide. The subjects are usually men with no structural heart disease or gastrointestinal pathology, and symptoms may vary from palpitations to lightheadedness or syncope.

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 ...
