TRUVACE RECORD VERSION record: TRV-2026-0040 version: 2 kind: revised reason: Model backfill: grounded claim, summary, sector, and trace validation timestamp: 2026-07-13T00:40:36.657532Z status: published lens: p_space sector: health headline: Accurhythm za420 (pause): FDA malfunction report involving AI dek: The FDA received a malfunction report involving Accurhythm za420 (pause), made by Medtronic, inc.. It was reported that true pause episodes were rejected as false by the artificial intelligence (ai) algorithm. no patient complications have been reported as a result of this event. gain_title: (none) problem_title: The Accurhythm za420 pause monitor's AI algorithm rejected true pause episodes as false, causing a detection failure trace_subject: (none) gain_reading: (none) problem_reading: The Accurhythm za420 pause monitor's AI algorithm rejected true pause episodes as false, causing a detection failure quick_read: The FDA received a malfunction report for the Accurhythm za420 (pause) device made by Medtronic, inc. The report stated that the device's artificial intelligence algorithm rejected true pause episodes as false. The source notes that no patient complications have been reported as a result of this event. If true pauses are misclassified, clinically relevant events could be missed, which matters for monitoring. What remains uncertain is how often this occurs, why the algorithm rejected the episodes, and whether any patients were affected, because the MAUDE entry is a surveillance signal not a verified clinical conclusion. limitation: Single MAUDE malfunction report; does not establish causality, incidence rate, or clinical outcome and requires investigation tag: Evidence-backed problem key_points: Device identified as Accurhythm za420 (pause) made by Medtronic, inc. | Report is part of FDA MAUDE surveillance data and is described as a signal for follow-up | Text explicitly states no patient complications have been reported as a result of this event rundown: The FDA received a malfunction report for the Accurhythm za420 (pause) device made by Medtronic, inc.

How to verify without trusting this page
Fetch the canonical text of any version from /api/record/TRV-2026-0040 and hash it yourself — for example shasum -a 256 on the saved canonical field. The result must equal content_hash, and each version’s text ends with prev:followed by the prior version’s hash (version 1 chains to 64 zeros). If a single character of any version had been altered since certification, the chain would not reproduce.
