Clinical Intake — Palpitations

A 67-year-old woman with a 15-year history of well-controlled hypertension and type 2 diabetes presents with a 4-month history of intermittent palpitations occurring every 6–8 weeks, each episode lasting several seconds and described as a sudden awareness of a rapid, irregular heartbeat without associated syncope, chest pain, or shortness of breath. Resting 12-lead ECG demonstrated normal sinus activity with occasional premature atrial contractions, and cardiac imaging confirmed preserved left ventricular function with an ejection fraction of 60% and no structural abnormality. Thyroid function and electrolyte panels are within normal limits. Dr. Whitfield recommends further evaluation to characterize the episodic nature of her cardiac events.
