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

Arrhythmic risk in elderly patients candidates to transcatheter aortic valve replacement. predicative role of repolarization temporal dispersion [PDF]
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?
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]
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 Tachyarrhythmias in Small Children [PDF]
An estimated 80,000-100,000 radiofrequency ablation (RFA) procedures are performed in the United States each year.1 Approximately 1% of these are performed on pediatric patients at centers that contribute data to the Pediatric Radiofrequency Registry.2 ...

Catheter Ablation of Atrial Tachycardia in a Giant Right Atrium
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.

RADIOFREQUENCY ABLATION IN ATRIAL TACHYCARDIA PAROXYSM ON EXAMPLE OF CLINICAL CASE
The disappearance of atrial tachycardia paroxysms after radiofrequency catheter ablation (RFA) of ectopic focus in a left atrium is presented on example of clinical case. Atrial tachycardia paroxysms disappeared after ablation completely.

Quality of Life in Patients with Implantable Cardioverter Defibrillators [PDF]
Background: The implantable cardioverter defibrillator (ICD) is a life saving device for individuals with life threatening ventricular arrhythmias. There is no doubt that it is a cost effective therapy in various congenital and acquired arrhythmogenic ...
