After a ventricular tachycardia ablation, what are the best things to keep it from coming back?

Ventricular tachycardia (VT) is a potentially life threatening heart rhythm disorder. Ablation is a procedure to interrupt the pathways that allow it to happen. People prone to sustained VT may have an underlying heart problem, such as coronary artery disease or heart failure. Treating those conditions further reduce the risk of VT recurrence.
