Posterior fast atrioventricular node pathways: Implications for radiofrequency catheter ablation of atrioventricular node reentrant tachycardia

Journal of the American College of Cardiology, 1996
This study sought to present evidence that fast atrioventricular (AV) node pathways with posterior exit sites may participate in typical AV node reentry.Catheter ablation of the slow AV node pathway in the posteroseptal right atrium is the preferred therapeutic approach in patients with AV node reentrant tachycardia.

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 ...

Radiofrequency Catheter Ablation for Atrioventricular Node Reentry Tachycardia with Multiple Slow Atrioventricular Node Pathways.

Japanese Circulation Journal, 1995
Catheter ablation was attempted in 2 patients with atrioventricular node reentry tachycardia which showed fast, intermediate and slow anterograde atrioventricular node pathways. Radiofrequency currents were applied within a restricted area of the tricuspid annulus between the His bundle and the ostium of the coronary sinus where presumed slow pathway ...

Transient unexpected improvement of AV conduction: What is the mechanism? [PDF]

, 2006
This ECG was recorded from a 93 year old patient with a previously documented third degree AV block and an underlying LBBB. The twelve lead ECG demonstrates sinus bradycardia at a rate of 52 beats per minute, a PR interval of 230 milliseconds, and a ...

Multiple Arrhythmogenic Substrate for Tachycardia in a Patient with Frequent Palpitations [PDF]

, 2005
We report a 26-year-old woman with frequent episodes of palpitation and dizziness. Resting electrocardiography showed no evidence of ventricular preexcitation.

A surgical resection case of myxoma arising from the posterior wall of the left atrium complicated with complete atrioventricular block

Journal of Cardiothoracic Surgery
An 80-year-old female was referred to our institution due to transient right upper limb weakness. Transthoracic and transesophageal echocardiography revealed a tumor in the left atrium. The tumor was attached to the posterior wall of the left atrium near
