An 89-year-old man is complaining of a "racing heart." He states his symptoms began while playing a card game with friends. He had an MI 15 years ago and a coronary artery bypass graft 5 years ago. His BP is 140/90 mm Hg and his ventilatory rate is 16 breaths/min. Breath sounds are clear and his tidal volume is adequate. His SpO2 on room air is 88%. Which of the following statements is true with regard to the management of this patient? A. The patient is unstable. Sedate the patient and defibrillate as quickly as possible. B. The patient is stable. Administration of IV verapamil is recommended for termination of the rhythm. C. The patient is stable. Administration of IV adenosine can be used as a therapeutic and diagnostic maneuver. D. The patient is unstable. Because there are recognizable QRS complexes on the monitor, synchronized cardioversion should be performed. B. Regular, monomorphic, wide-QRS tachycardia.
