Greta is in the hospital where they have just implanted a new device capable of controlling the heartbeat and preventing arrhythmias, which can be controlled with a smartphone application. Dr. Susan begins the testing. The device goes out of control and causes a strong arrhythmia in the girl. Greta begins to pant until her heart goes into fibrillation and cardiac arrest. The doctor and nurse begin CPR with chest compressions and AMBU bags. After a few cycles they decide to use the defibrillator, but they get no results. The cycles of CPR continue, until the girl recovers. The doctor and nurse's relief is short-lived. Greta has a new cardiac arrest. The rounds of CPR and AMBU bagging continue, the girl is stripped completely and intubated. Defibrillator shocks are numerous and increasingly powerful. After numerous attempts Dr. Susan is tired, she touches her chest, she doesn't seem to feel well. The last shock administered to Greta has an effect on her and the girl recovers, while Susan laboriously leaves the room. To be Continued... CPR, Chest Compressions, Defibrillator, Endotracheal Tube.
