What is the life expectancy for people with ventricular tachycardia? how serious is ventricular tachycardia, and what kind of treatment is available?

Most : Most forms of ventricular tachycardia (VT) are very serious, and require close management by a cardiologist. Conditions that cause scarring or enlargement of the heart can lead to vt, but sometimes VT happens by itself. Treating ventricular tachycardia is a multifaceted approach. If there is an underlying condition causing the vt, then that must be optimally treated. There are several medications available to help stabilize the heart rhythm and prevent episodes of vt, but these should be prescribed and monitored by an expert. Depending on the cause and severity of the vt, some patients also require defibrillators. A defibrillator is a device similar to a pacemaker, but with the capability to identify VT and convert the rhythm with an electrical shock.

Variable: Vt has a wide spectrum of severity. Some kinds cause no symptoms and are benign and others deteriorate rapidly to ventricular fibrillation and cause death. In the setting of hypertrophic cardiomyopathy (your other question), VT is more serious and may require placement of an icd. Icds have been shown to greatly improve prognosis.
