Overview
Ventricular tachycardia is a tachycardia, or fast heart rhythm that originates in one of the ventricles of the heart. This is a potentially life-threatening arrhythmia because it may lead to ventricular fibrillation and sudden death.
Causes
Common causes of ventricular tachycardia include ischemic heart disease, illicit drugs (cocaine and methamphetamine), structural heart disease (including congenital heart diseases such as Tetralogy of Fallot), inherited channelopathies, drug toxicity (digoxin, drugs that prolong the QT interval) and electrolyte disturbances(such as hypokalemia, hypomagnesemia, and hypocalcemia).
Treatment
Therapy may be directed at either terminating an episode of the arrhythmia or for suppressing a future episode from occurring. The treatment is tailored to the specific patient, with regard to how well the individual tolerates episodes of ventricular tachycardia, how frequently episodes occur, their comorbidities, and their wishes. The main treatments are categorised on the home page.
