She was found to be in ventricular fibrillation and was defibrillated 8 times without a single, even transient, conversion out of fibrillation. She was immediately intubated during continued compressions, then underwent a 9th defibrillation, which resulted in an organized rhythm at 42 minutes after initial arrest. References : 1.

She was never seen to be in ventricular fibrillation and was never defibrillated. Rather it is due to coronary insufficiency due to a tight left main or 3-vessel disease with inadequate coronary flow. Medics found her apneic and pulseless, began CPR, and she was found to be in asystole. BP gradually rose.

We rapidly defibrillated her, and with return of normal sinus rhythm. Several minutes later the patient developed V-fib again > 200J defibrillation with return to NSR. Rapid sequence intubation was performed for airway protection in setting of recurrent V-fib and defibrillations. Chest X-ray also showed pulmonary edema.

The arterial pressure waveform is transduced using the coronary catheter. Normally, the diameter of the coronary artery ostium is much greater than the diameter of the catheter so that catheter engagement does not significantly impair antegrade coronary perfusion. She was defibrillated perhaps 25 times.
