The patient reports that he does not feel weak or have any palpitations, and his vitals are normal. His medical history is only significant for hypertension, for which he takes diltiazem. He has no family history of heart disease and does not smoke. You attempt a carotid sinus massage, and you see that there are more dropped beats on the monitor.

Which of the following is the most appropriate next step in management?

A. Decrease his dose of diltiazem
B. Increase his dose of diltiazem
C. Cardioversion
D. Administer amiodarone
