The best management of a patient with witnessed transient ventricular fibrillation is electrical defibrillation; if the patient is judged to be in ventricular fibrillation, a defibrillator should be quickly brought to the bedside and the patient should be given electrical defibrillation therapy. The patient should be placed on a flat wooden bed and separated from the surrounding conductive material. If the patient does show transient ventricular fibrillation on the EKG, immediately bring the defibrillator to the bedside, turn on the power, and check the performance of the defibrillator. If the patient does need to be defibrillated, place the defibrillation electrodes immediately after a second judgment call. Synchronized DC defibrillation can be performed with a dose of 200 joules, and asynchronized DC defibrillation can be performed with a dose of 360 joules. Two defibrillations can usually be given to see if the patient’s ventricular fibrillation recovers.
