Summary: The aim of this study is to define the importance of non-invasive programmed stimulation (NIPS) in risk stratification of ventricular tachycardia (VT) recurrence after catheter ablation and to determine the optimal treatment strategy. The primary objective is to establish whether a new VT ablation based on NIPS inducibility will reduce the risk of VT recurrence compared to antiarrhythmic drug ther...

Summary: To investigate the effect of VTA ablation at the time of LVAD implant to see if it can reduce the incidence of VTA after surgery

Summary: The goal of this study to find out the efficacy of early rhythm therapy in patients with subclinical atrial fibrillation detected by Cardiac Electronic Implantable Devices. Early rhythm therapy includes antiarrhythmic drug, cardioversion, and catheter ablation. The general control group receives general management without the above atrial fibrillation rhythm control treatment. Researchers will com...
