Single-center Pilot Study to Evaluate the Interest of a Hybrid Connected Watch for Heart Rate Monitoring in Postoperative Cardiac Surgery
The objective of this single-center pilot study is, with the help of a connected watch, to show the absence of recurrence or maintenance of sinus rhythm in patients with a Post Operative Atrial Fibrillation (POAF) and to help treating cardiologists in the care of these patients.
Inclusion: Major with an indication for conventional cardiac surgery with de novo postoperative AF onset; Agreeing to participate in the study and having signed an informed consent; Agreeing to undergo 12 months of postoperative monitoring.
Exclusion: Patients implanted with a mechanical valve prosthesis pre-operatively or after surgery; Patient with a physical constraint to the measurement (arteriovenous fistula...); Patient with pre-operative AF; Patient who does not have a smartphone compatible with the connected watch; Patient unable to perform an ECG measurement independently; Minors; Pregnant or breast-feeding women; Adults under guardianship, under curatorship; Patients whose life expectancy is less than 1 year; Patients participating in another therapeutic trial likely to impact the evaluation criteria of the MONHYCARD study; Contraindication to long-term anticoagulants.
