Increased baseline ECG R-R dispersion predicts improvement in systolic function after atrial fibrillation ablation. [PDF]

, 2019
BackgroundAtrial fibrillation (AF) is associated with left ventricular (LV) systolic dysfunction which may improve after AF ablation. We hypothesised that increased ventricular irregularity, as measured by R-R dispersion on the baseline ECG, would ...

Electrophysiology Study for Complex Supraventricular Tachycardia in Congenital Heart Disease Patients With Single‐Ventricle Physiology

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundSupraventricular tachycardia (SVT) is common in complex congenital heart disease (CCHD) patients with single‐ventricle physiology and may cause hemodynamic deterioration.

Arrhythmic risk in elderly patients candidates to transcatheter aortic valve replacement. predicative role of repolarization temporal dispersion [PDF]

, 2019
Degenerative aortic valve stenosis (AS) is associated to ventricular arrhythmias and sudden cardiac death, as well as mental stress in specific patients. In such a context, substrate, autonomic imbalance as well as repolarization dispersion abnormalities ...

Narrow QRS Tachycardia with Alternate Wide QRS Beats: What is the Mechanism?

Indian Pacing and Electrophysiology Journal, 2008
A 44-year old lady underwent electrophysiology study for recurrent palpitations and documented narrow QRS regular tachycardia. The baseline ECG showed subtle preexcitation that was easily manifest on atrial pacing.

Electrocardiography in horses, part 2: how to read the equine ECG [PDF]

, 2010
The equine practitioner is faced with a wide variety of dysrhythmias, of which some are physiological. The recording of an exercise electrocardiogram (ECG) can help distinguish between physiological and pathological dysrhythmias, underlining the ...

Catheter Ablation of Atrial Tachycardia in a Giant Right Atrium

JACC: Case Reports, 2020
A 25-year-old male patient with a giant right atrium presented with atrial tachycardia. Electroanatomic mapping revealed micro–re-entry from a low-voltage zone in the region of the right atrial appendage.

Interesting response to ventricular overdrive pacing during regular narrow QRS tachycardia. What is the mechanism?

Indian Pacing and Electrophysiology Journal, 2020
33 year old gentleman has undergone an electrophysiology study for recurrent paroxysmal palpitation. During one of the episodes of palpitation a regular narrow QRS tachycardia was documented which has terminated with intravenous adenosine.
