Catheter ablation for refractory ventricular tachycardia early after acute myocardial infarction: management, electrophysiological characteristics, and outcomes
Authors' conclusion
Scar-related reentry is responsible for refractory VT early after AMI, and ablation at critical isthmus is effective in VT suppression.
