<unk> , which may have a similar etiology to cardiac arrest, is characterized as a compromise in the electrical activity of the heart often due to an ischemic event. The post-arrest patient who has recently obtained pulses, is dependent on prehospital care providers for ventilation assistance, arrhythmia correction through medication and blood pressure monitoring. Therefore insufficient care in any of these treatments may contribute to a<unk>  event. The lethal arrhythmia may be either ventricular fibrillation, ventricular tachycardia or asystole. A strong suspect that may be a critical contributor to<unk>  is the administration of chest compressions to the patient when the patient has already achieved a pulsatile rhythm. It is often difficult to determine the presence of a pulse in a cardiac arrest patient, thus chest compressions may be given by the unaware resuscitator and this added stress on the heart may contribute to a<unk>  event.
