Introduction

A 20-year-old female college student presents to the college health service with complaints of an irregular heart rate. She does not have any known cardiac disease but has noted palpitations in the past. However, the palpitations have lasted for only 1 to 2 hours and have been infrequent. She has never seen a physician for these palpitations. However, she has never noted her heartbeat to be irregular.
