When the impulses are properly synchronized, you have a normal heartbeat. Ventricular tachycardia occurs when the delivery of impulses is out of sync, causing the lower chambers to beat too fast. This ...

indicated for catheter ablation of drug refractory ventricular tachycardia ("VT") in accordance with current treatment guidelines. The results of the study will be used to obtain premarket ...

Atrioventricular nodal reentrant tachycardia (AVNRT) is a rapid, irregular heartbeat that starts suddenly and without warning and may stop just as abruptly. It is a common type of what's called ...

Such techniques can be automatically applied using implantable cardioverter defibrillators (ICDs) and offer the potential for painless termination of ventricular tachycardia (VT). Reduction in ...

viii In this example relative refractory conduction delay would ... x It is possible (though unlikely) that tachycardia is in fact AVNRT yet atrial activation following the PVC is different ...

Background: Cardiogenic shock (CS) is the most severe form of heart failure (HF), resulting in high early and long-term mortality. Characteristics of CS secondary to supraventricular tachycardia (SVT) ...

It may be that such patients have a low incidence of sudden death, but it does not necessarily follow that this is an effect of ablation, given the incidence of recurrent ventricular tachycardia.
