The patient in asystole during cardiac arrest, has a very poor prognosis. But is it really asystole? Is there benefit in giving one shock to the patient? Surely we need to look at all the leads and increase the amplitude, to see of this is low amplitude VF. Even if we find low amplitude VF, will we be able to successfully defibrillate them? Aren't we supposed to perform CPR to increase the amplitude of the VF waveform?....we've been doing this, with no success. Delivering one shock may be very appropriate.
