Overview
Ventricular tachycardia can cause life-threatening or fatal hemodynamic compromise or it can degenerate into a life-threatening rhythm called ventricular fibrillation. In general, supraventricular tachycardia with aberrancy is generally better tolerated and is not necessarily a medical emergency. Common complications of ventricular tachycardia include sudden cardiac death, cardiomyopathy, ventricular fibrillation, and infection related to ICD. Prognosis of ventricular tachycardia in patients largely depends upon the presence and severity of underlying cardiac disease.
Natural History
* Ventricular arrhythmia include the range from premature ventricular contraction (PVC]] to ventricular fibrillation.
- Ventricular tachycardia can cause life-threatening or fatal hemodynamic compromise or it can degenerate into a life-threatening rhythm called ventricular fibrillation. In general, supraventricular tachycardia with aberrancy is generally better tolerated and is not necessarily a medical emergency. An exception is if the the wide complex tachycardia is due to atrial fibrillation conducting down a bypass track such as is seen in Wolff-Parkinson-White syndrome (WPW) in which case the rhythm can degenerate into life-threatening ventricular fibrillation.
Complications
Common complications of ventricular tachycardia include:[1]
- Sudden cardiac death
- Cardiomyopathy
- Infection related to implantable cardioverter defibrillator
- Ventricular fibrillation
Prognosis
- Prognosis of ventricular tachycardia in patients largely depends upon the presence and severity of underlying cardiac disease.[2][3]
- In patients without evidence of ischemia or structural heart disease, prognosis is generally good.
- Meanwhile, patients with underlying cardiac pathology may require lifelong medical therapy with medications, catheter ablation, and/or implantable cardioverter defibrillator (ICD) placement.
