This is a prospective, randomized, controlled trial to investigate the efficacy of radiofrequency catheter ablation (RFCA) combined with guideline-directed medical therapy (GDMT) compared to GDMT alone in patients with polymorphic ventricular tachycardia (PMVT) and coexisting heart failure (HF). The study aims to evaluate whether the addition of RFCA can lead to superior improvements in cardiac function, clinical outcomes, and serum biomarkers at a 6-month follow-up.
