Antiarrhythmics or Ablation for Ventricular Tachycardia 2

Inclusion Criteria: * Prior Myocardial Infarction and * One of the following VT events while not being treated with amiodarone, sotalol, or another class I or class III antiarrhythmic drug) within the last 6 months: * Sustained monomorphic VT documented on 12-lead ECG or rhythm strip terminated by pharmacologic means or DC cardioversion * ≥3 episodes of VT treated with antitachycardia pacing (ATP), at least one of which was symptomatic * ≥ 5 episodes of VT treated with antitachycardia pacing (ATP) regardless of symptoms * ≥1 appropriate ICD shocks, * ≥3 VT episodes within 24 hours Exclusion Criteria: * Unable or unwilling to provide informed consent. * Active ischemia (acute thrombus diagnosed by coronary angiography, or dynamic ST segment changes demonstrated on ECG) or another reversible cause of VT (e.g. drug-induced arrhythmia), had recent acute coronary syndrome within 30 days, coronary revascularization (\<90 days bypass surgery, \<30 days percutaneous coronary intervention), or have CCS functional class IV angina. Note that biomarker level elevation alone after ventricular arrhythmias does not denote acute coronary syndrome or active ischemia. * Are ineligible to take the antiarrhythmic drug to which they would be assigned due to allergy, intolerance or contraindication * Are known to have protruding left ventricular thrombus or mechanical aortic and mitral valves * Have had a prior catheter ablation procedure for VT * Presenting arrhythmia: polymorphic V…
