A condition in which the lower chambers of the heart (ventricles) beat very quickly.
Ventricular tachycardia occurs due to a problem with the heart's electrical impulses. The condition may develop as a complication of a heart attack or may occur in people with certain conditions, such as valvular heart disease.
Symptoms include chest pain, fainting, dizziness, and shortness of breath.
Treatment options include medication to slow the heart rate, surgery, and an implantable device.
