A 70-year-old woman with a history of hypertension, which is being treated with a beta-blocker and an angiotensin-converting enzyme inhibitor, presents to her primary care provider with complaints of increasing fatigue and lightheadedness. Her blood pressure, previously well controlled, is noted to be 180/100 mmHg with an irregular pulse. A 12-lead ECG is obtained.
