Medtronic recalls specific models of ICM LNQ22 LINQ II insertable cardiac monitors due to potential signal interference that may affect heart rhythm recordings. This issue differs from normal noise patterns caused by device movement or external factors.
Lower-risk recall
It may create the potential for amplified noise and/or overall signal reduction of the ICM, which may interfere with intended recordings of heart rhythms. This noise pattern is different from occasional noise due to device position/migration, patient activity, or external electromagnetic interference.
