Effect of pacing the right ventricular mid-septum tract in patients with permanent atrial fibrillation and low ejection fraction.

abstract：INTRODUCTION:As treatment options for ventricular tachycardia (VT) continue to evolve, the use of radiofrequency catheter ablation is rapidly expanding. However, in the presence of multiple morphologies of VT, achieving successful results may seem less likely. We report two patients with multiple morphologies of VT who...
