Introduction: Atrioventricular nodal reentrant tachycardia (AVNRT) is one of the most common regular supraventricular arrhythmias referred for catheter ablation (CA). In Poland, several families with ...

Peter Spector, M.D.; Nicole Habel, M.D. The first step in an electrophysiologic study is passive observation. One can examine the initiation and termination of tachycardia for clues as to its ...

AVNRT commonly affects young, healthy women without structural heart disease. 5 Common tachycardic risk factors include drug induction, caffeine, prior history of heart disease, alcohol use, stress, ...

This is a narrow QRS complex tachycardia with a very fast heart rate (about 250 beats per minute). It is quite difficult to indentify any P wave activity to determine the exact etiology. Most commonly ...

Ablation of supraventricular tachycardia in elderly persons presents a challenging problem to electrophysiologists. Friable cardiac structures, prone to catheter perforation, comorbid cardiovascular ...
