Tracy is in the ER after suffering a heart attack and being revived from cardiac arrest at her home. Her sweater is immediately removed and her chest is left bare. The doctor applies the electrodes and can begin monitoring the girl's pulse. They immediately realize that she is not regular, Tracy struggles to breathe and the situation is getting more and more serious. Suddenly the situation escalates. Tracy's heart goes into fibrillation and the doctor starts CPR. The rescuers carry out several cycles, also using the AMBU, until it is decided to use the defibrillator. Her plates are placed on the girl's bare chest but the shocks have no effect, but cause asystole. The compressions resume, deep, numerous, and the AMBU continues to pack. Finally the heart rhythm becomes shockable again and the shocks follow one another, but without obtaining any results. Rescuers continue with maneuvers, numerous cycles of CPR, AMBU bagging, and defibrillator shocks. After several minutes the rhythm finally returns and quickly normalizes, Tracy recovers and opens her eyes. CPR, AMBU, Defibrillator, Chest compressions. Various camera angles. Completely naked
