As a medical professional with expertise in emergency medicine, I can provide you with an informed response to your question regarding the treatment of pulseless ventricular tachycardia (VT). In the case of pulseless VT, immediate defibrillation is the recommended treatment. Unlike other forms of unstable VT, which may be treated with synchronized cardioversion, pulseless VT requires unsynchronized shocks. The initial shock for a biphasic defibrillator should be delivered at a dose of 150-200 Joules (J). If the first shock does not restore a perfusing rhythm, subsequent shocks should be given at the same or higher energy level. read more >>

Pulseless VT. Pulseless VT, in contrast to other unstable VT rhythms, is treated with immediate defibrillation. High-dose unsynchronized energy should be used. The initial shock dose on a biphasic defibrillator is 150-200 J, followed by an equal or higher shock dose for subsequent shocks.read more >>
