Paroxysmal Ventricular Tachycardia

Paroxysmal ventricular tachycardia is intermittent, wide-QRS ventricular tachycardia, due to reentry/ automaticity in structural heart disease (ischemic cardiomyopathy) or idiopathic VT. Clinical: palpitations, syncope, hemodynamic instability. Treatment: acute - amiodarone/lidocaine/cardioversion if unstable; identify cause (ischemia/cardiomyopathy); treat underlying disease; ICD for structural heart disease; catheter ablation for recurrent/idiopathic VT.

Common Symptoms

Palpitations/syncope; wide-QRS VT; structural heart disease; hemodynamic instability if sustained

Causes and Pathogenesis

Reentry/automaticity in diseased myocardium causes ventricular tachycardia.

Treatment

Amiodarone/cardioversion acute; treat cause; ICD for structural disease; ablation for recurrent

Preventive Measures

Treat ischemia/cardiomyopathy; ICD for SCD risk.

Department to Visit

It is recommended to visit the Cardiology/EP department; an appointment can be booked on this platform before the visit.
