Provides a brief overview of the mechanism and process of catheter ablation for ventricular tachycardia.
Answers are grounded in this paper and cite their sources.
Does not alter clinical practice for VT ablation; leaves open need for updated randomized evidence on long-term outcomes.
Catheter ablation of ventricular tachycardia involves identifying the mechanism (a focus with abnormal impulse formation or a reentrant circuit), mapping the VT, and using radiofrequency current to ablate the tissue involved.
