There is a run of polymorphic ventricular tachycardia — which given the QT prolongation, qualifies as Torsades de Points ( TdP ). This episode self terminated before defibrillation was possible.

Otherwise vitals after intubation were only notable for tachycardia. An initial EKG was obtained: Computer read: sinus tachycardia, early acute anterior infarct. She was ventilated by bag-valve-mask by EMS on arrival and was quickly intubated with etomidate and succinylcholine. A rectal temperature was obtained which read 107.9

Several 200 J shocks did not terminate the VF, so a second defibrillator was applied for double sequential defibrillation with 400 J. She was defibrillated perhaps 25 times. Propranolol versus Metoprolol for treatment of electrical storm in patients with implantable cardioverter-defibrillator. SanzRuiz, R., Solis, J., &
