8) A 45-year-old male suddenly loses consciousness and falls to the ground. He has been previously healthy and has been on no medications. There is no obvious evidence of trauma.

A. Obtain vital signs
B. Administer a bolus of intravenous lidocaine
C. Administer a thrombolytic agent
D. Perform asynchronous cardioversion
E. Perform synchronous cardioversion

D. The patient is in ventricular tachycardia and is hemodynamically unstable as apparent from the loss of consciousness. He should be emergently cardioverted asynchronously with 200 joules of energy initially.

He is hemodynamically unstable, as apparent from his loss of consciousness. Precious time will be lost by obtaining vital signs (choice A) if cardioversion can be done now.

A lidocaine bolus should be given once a pulse and sinus rhythm is obtained to keep him out of ventricular tachycardia. This is especially beneficial if the event is ischemic in origin (choice B).

He may be having an infarct, and this may be the cause of his ventricular tachycardia. Emergently, the physician needs to restore sinus rhythm and then the man will be treated for myocardial infarction, if indicated (choice C).

If the patient were stable, synchronous cardioversion could be attempted (choice E).
