Abnormal ventricular muscle that becomes self activated (automaticity) vt can occur in an otherwise healthy, or structurally normal heart. It can also occur as a result of damage or scar in the heart from prior heart disease. Vt that occurs in the setting of structural heart disease is more concerning and often can be life threatening.
