headline: Reveal linq: FDA malfunction report involving AI
dek: The FDA received a malfunction report involving Reveal linq, made by Medtronic europe sarl. It was reported that the implantable cardiac monitor (icm) experienced false pause episodes due to undersensing. it was reported that representative stated the customer is concerned that the artificial intelligence (ai) algorithm adjudicated some pause episodes as false when they determined to be true. the icm remains in the patient. no patient complications have been reported as a result of this event.

problem_title: Customer concern that the Reveal LINQ implantable monitor's AI adjudication classified true pause episodes as false, following undersensing and false pause episodes

problem_reading: Customer concern that the Reveal LINQ implantable monitor's AI adjudication classified true pause episodes as false, following undersensing and false pause episodes
quick_read: The FDA received a malfunction report for the Reveal LINQ implantable cardiac monitor made by Medtronic europe sarl. The report describes false pause episodes due to undersensing and a customer concern that the device's AI algorithm adjudicated episodes the customer considered true pauses as false. The device remains implanted.

If AI adjudication incorrectly dismisses true pauses, clinically relevant arrhythmias could be missed or delayed in review, which matters for cardiac monitoring. What remains uncertain is whether the adjudication was actually incorrect, how often this occurs, and whether any harm resulted, as the report notes no complications and MAUDE data is a signal for follow-up not a verified conclusion.
limitation: Single MAUDE malfunction report; does not establish causality, incidence rate, or clinical outcome
tag: Evidence-backed problem
key_points: Device identified as Reveal linq made by Medtronic europe sarl and classified as an implantable cardiac monitor (icm) | Report states the icm remains in the patient after the event | Report states no patient complications have been reported as a result of this event | Report is described as part of FDA's MAUDE surveillance data and should be read as a signal for follow-up
