Shelly is an ambulance breathing heavily. The nurses check her BP and cut off ALL of her clothes. They put on EKG electrodes, and IV and later they give her O2 from a mask. Shelly's breathing is very bad. Suddenly her heart goes to ventricular tachycardia and soon flat lines. The nurses start CPR and bagging her, charging the defibrillator. Following many rounds of CPR her pulse comes back. The ambulance starts to go to the hospital. Very long breathless scenes in this clip and very nice, large defibrillations.
