Electrocardiographic Manifestations of Dual Atrioventricular Node Conduction During Sinus Rhythm [PDF]

, 1997
Objectives. The objective of this study was to correlate electrocardiographic (ECG) PR interval changes during normal sinus rhythm with recent observations regarding the anatomy and physiology of the dual, slow and fast atrioventricular (AV) pathways ...

Treatment of Acute Atrial Fibrillation: Ventricular Rate Control and Restoration of Sinus Rhythm

, 2000
Atrial fibrillation (AF) is a familiar arrhythmia seen in the emergency department and the general population. In the past it was treated in the majority of cases by controlling the ventricular rate, whether the AF is acute or chronic.

Chronic beta-adrenoceptor blockade and human atrial cell electrophysiology: evidence of pharmacological remodelling [PDF]

, 2003
<b>Objective:</b> Chronic beta-adrenoceptor antagonist (β-blocker) treatment reduces the incidence of reversion to AF in patients, possibly via an adaptive myocardial response.

Antegrade and Retrograde Decremental Conduction Properties of an Accessory Pathway Associated with the Coronary Sinus Musculature

Indian Pacing and Electrophysiology Journal, 2015
A 32-year-old man underwent catheter ablation of an orthodromic atrioventricular reentrant tachycardia. The sinus rhythm electrocardiogram exhibited a normal PQ interval and no delta waves, but atrial pacing produced a prolonged PQ interval and wide QRS ...

Antiarrhythmics for maintaining sinus rhythm after cardioversion of atrial fibrillation

, 2020
International audienceBackground : Atrial fibrillation is the most frequent sustained arrhythmia. Atrial fibrillation frequently recurs after restoration of normal sinus rhythm.

Varying atrial activation in sinus rhythm.

, 2018
A. Surface ECG and intracardiac electrograms showing varying P wave morphology and CS activation during sinus rhythm without changing heart rate. Note CS activation is distal to proximal on the first two beats, but then reverses by the fourth beat.

Shortening of ventriculoatrial interval after ablation of an accessory pathway

Indian Pacing and Electrophysiology Journal, 2006
A 21-year old man with history of 8 year palpitation was referred for electrophysiologic study and possible radiofrequency ablation. Physical examination and transthoracic echocardiographic study did not disclose any abnormality.

SUCCESS OF ELECTIVE CARDIOVERSION IN PERSISTENT ATRIAL FIBRILLATION PATIENTS WITH OR WITHOUT DIASTOLIC DYSFUNCTION AS ASSESSED BY LEFT ATRIAL VOLUME INDEX

Pakistan Armed Forces Medical Journal, 2019
Objective: To compare the success of elective electro-cardioversion of persistent AF patients presented with or without diastolic dysfunction as assessed by left atrial volume index (LAVI); and to compare the relationship between recurrence of AF after ...
