Does spontaneous ventricular tachycardia pleomorphism affect the acute and long-term success rate of radiofrequency catheter ablation in patients with post-myocardial infarction ventricular tachycardia?
Spontaneous ventricular tachycardia pleomorphism in patients with prior myocardial infarction is a strong predictor of lower acute and long-term success rates following radiofrequency catheter ablation.
