Non-sustained VT lasts for less than 30 seconds and is asymptomatic. Ventricular tachycardia should be described by type (monomorphic or polymorphic), duration (sustained or non-sustained ...

Polymorphic ventricular tachycardia (a.k.a. Torsades de Pointes) is best treated with intravenous magnesium. Patients with a prolonged QT interval have a higher risk of developing polymorphic VT.

Ventricular tachycardia (V-tach or VT) is when the lower chamber of the heart beats too fast to pump efficiently. This reduces the amount of oxygenated blood the rest of the body receives.

Such techniques can be automatically applied using implantable cardioverter defibrillators (ICDs) and offer the potential for painless termination of ventricular tachycardia (VT). Reduction in ...
