    *   The firm failed to adequately analyze approximately 4,014 complaints (05/02/2022 - 07/19/2024) related to CCT personnel misreading arrhythmia data, which led to misclassified data for diagnosis.
    *   No CAPA or health hazard evaluation was initiated, nor was a risk analysis performed for these recurring quality problems.
    *   The firm's quality metric calculations ([(b) (4)]) are not all-inclusive due to missing relevant data inputs.
    *   A plan implemented around 07/02/2024 to not report algorithm misread/misinterpretation events as malfunctions under 21 CFR § 803 lacks established procedures for retroactive or
