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

Catheter ablation was not the first-line treatment for supraventricular tachycardia (SVT) for most patients referred to a tertiary center, a study shows, with investigators suggesting the procedure is ...

In recognition of SVT Awareness Day, the Heart Rhythm Society (HRS) and Milestone Pharmaceuticals are partnering to expand ...

Sometimes, doctors don't know what sets off the racing, thumping heartbeat caused by supraventricular tachycardia (SVT). What they do know for certain: It starts in the upper chambers of your heart ...

The electrophysiologic mechanism may be due to either enhanced automaticity or triggered activity. In contrast to the paroxysmal variety, the nonparoxysmal type develops gradually and disappears ...
