Identification and management of ventricular tachycardia

J Indian Med Assoc. 2003 Feb;101(2):62-5, 95.


Recognising ventricular origin of a broad QRS tachycardia helps to appropriately identify and manage patients with ventricular tachycardia (VT) in the emergency. Relatively simple clinical and ECG clues help in reaching the correct diagnosis in the majority of patients. Management strategies vary with the clinical diagnosis and an implantable cardioverter defibrillator (ICD) is indicated for chronic prophylactic therapy in patients with coronary artery disease and serious ventricular arrhythmias, especially in those with ventricular dysfunction. The role of this device in patients with stable VT and ejection fractions > 0.35 deserves closer scrutiny. Radiofrequency ablation mostly plays an adjunctive role. Anti-arrhythmic drugs (amiodarone/sotalol and beta-blockers) are required to prevent frequent recurrences. A hybrid approach combining all these therapeutic modalities is often needed. Prognosis in patients with specific VT syndromes such as right ventricular outflow VT, left ventricular fascicular VT and left ventricular outflow VT is excellent with drugs. Radiofrequency ablation is curative in such syndromes.
