PO-05-078 SHOCK REDUCTION THROUGH EARLY DELIVERY OF ANTITACHYCARDIA PACING FOR FAST VENTRICULAR TACHYCARDIAS

Shock reduction using antitachycardia pacing for spontaneous rapid ventricular tachycardia in patients with coronary artery disease.

BACKGROUND Implantable cardioverter-defibrillators (ICDs) can terminate some ventricular tachycardias (VTs) painlessly with antitachycardia pacing (ATP). ATP has not routinely been applied for VT >188 bpm because of concerns about efficacy, risk of acceleration, and delay of definitive shock therapy. This prospective, multicenter study evaluated the efficacy of empirical ATP to terminate fast V...

Implantable Cardioverter Defibrillator Shock Despite Termination of Ventricular Tachycardia by Antitachycardia Pacing During Charging

Antitachycardia pacing for ventricular tachycardia using implantable cardioverter defibrillators:.

Antitachycardia pacing (ATP) refers to the use of pacing stimulation techniques for termination of tachyarrhythmias. Such techniques can be automatically applied using implantable cardioverter defibrillators (ICDs) and offer the potential for painless termination of ventricular tachycardia (VT). Reduction in painful shocks may improve patient quality-of-life (QOL) and extend ICD pulse generator...

Optimizing Antitachycardia Pacing

Implantable cardioverter-defibrillators (ICDs) substantially reduce sudden cardiac death. Paradoxically, even though ICDs are implanted to prevent sudden cardiac death by delivering therapies, appropriate and inappropriate ICD shocks have been associated with an increased risk of mortality.1 However, patients treated with ICD shocks show even poorer survival than patients treated with antitachy...

Termination of Ventricular Tachycardia with Antitachycardia Pacing after Ineffective Shock Therapy in an ICD Recipient with Hypertrophic Cardiomyopathy

Implantable Cardioverter Defibrillator (ICD) implantation is the only established therapy for primary or secondary prevention of sudden cardiac death in patients with Hypertrophic Cardiomyopathy (HCM). Ineffectiveness of shock therapy for the termination of potentially fatal ventricular arrhythmias in ICD recipients is rare in the presence of appropriate arrhythmia detection by the device. We r...
