A patient in the Surgical Trauma Intensive Care Unit (STICU) develops a sudden onset of narrow-complex tachycardia with a rate of 220 beats per minute. The patient’s blood pressure is 124/64 and the pulse oximetry is 99%. The patient has vascular access in the right arm and has not been given any vasoactive drugs. A 12-lead ECG confirms supraventricular tachycardia (SVT) with no evidence of cardiac ischemia. The heart rate has not responded to a modified valsalva maneuver. What is your next action?
