Question 1 (0.5 points)

Mr. Smith was seen by the emergency medical technicians (EMTs) and found to have an extremely rapid heartbeat. He was also sweating profusely and was breathing rapidly.

Lidocaine was given to the patient while in the ambulance and by the time he reached the ER, his heart rate was between 75 and 80 with sinus rhythm. He had excellent ST segments and T waves. Blood pressure was 156/88. He had strong carotid pulses bilaterally. No murmurs were heard.

A cardiac monitor was applied and observed for any EKG change. The patient did not have any episodes of hypotension and no further arrhythmia was noted. There was no evidence to indicate ordering cardiac enzyme studies, and the patient was discharged to be followed by his regular physician.
