A Smartwatch Heart Rate Monitor Prompts an Unusual Diagnosis
Abstract
We report the case of a 54-year-old woman who presented for cardiological evaluation having noted a decline in her heart rate on her wearable heart rate monitor. She was found to be in 2:1 atrioventricular block. Subsequent evaluation revealed cardiac and pulmonary sarcoidosis, treated with steroids and implantable cardioverter-defibrillator placement.
