Atrial Anomalies Predict Silent Atrial Fibrillation Detected by Implantable Cardiac Monitor in Cryptogenic Stroke

ICM implant 3-4 days after the stroke and prior to discharge. All devices (Abbott Confirm or Jot) were implanted subcutaneously under local anaesthesia in the left chest region and programmed with an specific algorithm for AF detection set at 30 seconds for detection. All patients were included in remote monitoring system (Merlin), which was programmed to send alerts in case of registering episodes qualifying for AF detection, and a monthly routine registration. All ICM recordings were reviewed by a specialized cardiologist.
