Abstract

Bifascicular block has the potential risk of progression to complete heart block. Typically, monitoring for symptoms and heart rate guides timing for definitive pacemaker therapy. Current monitoring devices being used include Holter, event recorder, and implantable loop recorder. We present a case of a 72-year-old male with a history of coronary artery disease coronary artery bypass graft surgery and bifascicular block who presented to the hospital with syncope which required emergent transvenous pacemaker prior to permanent pacemaker placement. About 2 weeks prior to presentation, he had a syncopal spell while he was wearing his ambulatory wrist heart monitor “a Fitbit”. Upon review of the Fitbit heart rate monitor, the Fitbit had correctly recognized bradycardia during his syncopal spell. We report a case of a Fitbit correctly identifying advancing paroxysmal complete heart block. The Fitbit and other wearable wrist monitors maybe an alternative way to monitor patients long-term at increased risk for progression to complete heart block.
