A 6 month old patient who is in the ICU following cardiac surgery for a congenital defect develops atrial flutter with an atrial rate of 300 beats/min and second degreee (2:1) AV node block. A 3rd year medical student inadvertantly administers quinidine, instead of propranolol,and the patient's ventricular rate skyrockets to 300 beats/min. The patient faints. This most likely occured because quinidine is:
A. a partial beta agonist
B. antimuscarinic
C. a sodium channel blocker
D. a potassium channel blocker
E. able to increase vagal tone
