Treatment for Ventricular Tachycardia

Acute Management Based on Hemodynamic Status

The European Society of Cardiology recommends immediate direct current cardioversion for patients with sustained VT who are hemodynamically unstable (syncopal VT) 1, 3
For patients who are hypotensive but conscious, immediate sedation should be given before cardioversion, as recommended by the European Heart Journal 1
In cases of in-hospital cardiac arrest due to VT, immediate defibrillation should be attempted, according to the European Heart Journal 2
For out-of-hospital cardiac arrest, cardiopulmonary resuscitation with chest compression should be performed immediately until defibrillation is possible, as recommended by the European Heart Journal 2

The American Heart Association recommends procainamide as a first-line pharmacological choice for monomorphic VT without severe heart failure or acute MI, with a dosage of 10 mg/kg IV at 50-100 mg/min over 10-20 minutes 1, 4
Amiodarone is recommended for patients with heart failure or suspected ischemia, as it can reduce the number of life-threatening arrhythmias, required shocks, and episodes of symptomatic sustained VT 1, 4
Sotalol may be considered for hemodynamically stable sustained monomorphic VT, including patients with acute myocardial infarction, with a recommendation from the American College of Cardiology 4
Beta-blockers may be useful for preventing recurrence and late conversion in refractory ventricular tachyarrhythmias, particularly in catecholaminergic polymorphic VT, as recommended by the Journal of the American College of Cardiology 4, 5

The European Society of Cardiology recommends urgent catheter ablation in patients with scar-related heart disease presenting with incessant VT or electrical storm 1
Catheter ablation is recommended in patients with ischemic heart disease and recurrent ICD shocks due to sustained VT, as well as after a first episode of sustained VT in patients with ischemic heart disease and an ICD 1
For polymorphic VT refractory to drug treatment, Purkinje-fiber triggered polymorphic VT may be amenable to catheter ablation, according to the European Heart Journal 1

Beta-blockers are the cornerstone of treatment for catecholaminergic polymorphic VT, with a recommendation from the Journal of the American College of Cardiology 5
For recurrent sustained VT or syncope despite beta-blocker therapy, consider combination therapy with flecainide, left cardiac sympathetic denervation, and/or ICD, as recommended by the Journal of the American College of Cardiology 5

Intravenous lidocaine is only moderately effective in VT and less effective than procainamide, sotalol, or amiodarone, according to Circulation 4, 6
For patients with an ICD, defibrillator patches should be placed on the chest wall at least 8 cm from the generator position, as recommended by the European Heart Journal 3
