When ventricular fibrillation occurs, because the heart stops beating effectively and there is no blood supply to the brain, the patient will experience a loss of consciousness, eyes rolled up, and in some cases, a typical Asseizure. An Asperger’s attack means that the patient will cry out, followed by twitching of the limbs, followed by loss of consciousness, respiratory and cardiac arrest, and so on. Once ventricular fibrillation occurs, CPR should be performed immediately or the patient’s life will be in danger. The most effective way to terminate an episode of ventricular fibrillation is electrical defibrillation, which involves passing an electric current through the patient’s heart via a defibrillator, thereby terminating the episode of ventricular fibrillation. There are two types of electrode placement for defibrillation, one is anterolateral, where one electrode is placed on the right side of the patient’s sternum between the second intercostal space, i.e., above the right nipple, and the other electrode is placed on the left side between the fifth intercostal space and the mid-axillary line, i.e., to the lower left of the left nipple. The second placement was an anterior-posterior position, in which one electrode plate was still placed on the second intercostal space on the right side of the sternum and the other electrode plate was placed on the left side behind the scapula, and then asynchronous electrical defibrillation was selected. Typically, 360 J of energy is selected for unidirectional waves and 200 J of energy for bidirectional fluctuations. For electrical defibrillation, the electrode plates were coated with a conductive paste, placed in the above position, and then the patient was again identified as having a defibrillatable heart rate, i.e., ventricular fibrillation. Subsequently, the charging button was pressed and charged according to the preset number of energies, and after charging was completed, others were instructed to leave the patient to avoid electrocution, and then discharged at the same time, and chest compressions were given to the patient immediately after discharging. Generally speaking, after the termination of ventricular fibrillation, the patient will experience a return of consciousness, heartbeat and respiration, which suggests that defibrillation is successful.
