When you enter the room, you find the patient is an elderly gentleman and presumably not an elite athlete. He is lying on his back and said that he has felt funny for about an hour. He reports some dizziness and some mild chest pain. He almost fell while going to the bathroom. The nursing student adds that he has high blood pressure and is on a beta-blocker. What do you suspect is happening to this patient?
a) Acute myocardial infarction
b) Hypoglycemia
c) Atrial fibrillation
d) Symptomatic bradycardia
