Case :
A 71-year-old woman collapsed while working as a grocery store cashier. CPR was initiated 5 minutes later and an automated external defibrillator (AED) revealed TdP. She was defibrillated and returned to sinus rhythm after a down time of 8 minutes. On arrival to a community hospital, her vitals included BP 120/60, HR 78, RR 20, and O2 saturation 99%. She was afebrile and semiconscious. Labs revealed severe hypokalemia (2.6?mmol/L) and normal cardiac enzymes. ECG demonstrated sinus rhythm with a prolonged QTc of 544?msec. A presumed diagnosis of ischemic polymorphic ventricular tachycardia was made and she was treated with 150?mg of amiodarone followed by infusion at 60?mg/hour. She subsequently developed hypotension with a BP of 80/60 and dopamine was administered at 15?mcg/kg/hr. Her pressure improved and potassium was given to correct hypokalemia. A temporary pacing wire was not inserted....
