You see a patient in cardiology outpatients who was recently seen on the ambulatory medical unit following a 48-Hour Holter monitor which was done for symptoms of lightheadedness at work. He works as an office receptionist and has suffered from hypertension for over 10 years, which is meant to be managed with diet and lifestyle. You note the report of the Holter shows intermittent runs of Mobitz type 1 AV-block with a PR-interval of 280ms. A resting 12-lead ECG today shows a PR-interval of 275ms with prolongation of PR-interval before loss of an associated QRS. He asks you how you will manage his symptoms.
