Personalized Heart Digital Twins Detect Substrate Abnormalities in Scar-Dependent Ventricular Tachycardia

Circulation

Circulation, Ahead of Print. BACKGROUND:Current outcomes from catheter ablation for scar-dependent ventricular tachycardia (VT) are limited by high recurrence rates and long procedure durations. Rapid-pacing protocols were used to induce VTs and to define the VT circuits.

Approach to the Diagnosis and Management of Complex Fascicular Ventricular Tachycardias

Circulation: Arrhythmia and Electrophysiology

Circulation: Arrhythmia and Electrophysiology, Ahead of Print. Complex ventricular tachycardias involving the fascicular system (fascicular ventricular tachycardias [FVTs]) can be challenging. To summarize, 5 cases had prior ablation with 2 previously misdiagnosed as supraventricular tachycardia.

Circulation: Arrhythmia and Electrophysiology

Circulation: Arrhythmia and Electrophysiology, Ahead of Print. During early childhood, 50% of patients develop multifocal atrial tachycardia, a treatment-resistant tachyarrhythmia of unknown pathogenesis. BACKGROUND:GermlineHRASgain-of-function pathogenic variants cause Costello syndrome (CS).
