    Intended Use

    The model MT series digital thermometers (MT-201, 301, 402 and 403) are intended to measure the human body temperature in regular mode orally, rectally or under the arm. The devices are reusable for clinical or home use on people of all ages.

    The device model MT-405 is intended to measure oral temperature only. It is reusable for clinical or home use for children under the age of four.

    Device Description

    Digital Thermometer Model MT series (MT-201, MT-301, MT-402, MT-403 and MT-405) enable fast and reliable measurements. These thermometers provide very high clinical accuracy, and have been designed to provide maximum userfriendliness.

    The basic principle of these thermometers is that a change of thermistor resistance, caused by changes of temperature, is converted to changes of frequency of R-C oscillator circuit. Therefore, temperature can be given by measuring the frequency of the oscillator.

    For a given time period by applying to R-C oscillator circuit, changes of temperature will correspond to changes of pulse number.

    Detailed Study Information (Based on the provided text, much of this is not available):

    2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

    • The document states "Controlled human clinical studies were conducted using the digital thermometer model MI series."
    • Sample size for test set: Not specified.
    • Data provenance: Not specified (e.g., country of origin, retrospective or prospective).

    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

    • Not specified. The specific method for establishing "ground truth" (e.g., how the reference temperature was obtained in the clinical studies) is not detailed.

    4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

    • Not specified.

    5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

    • Not applicable. This device is a digital thermometer, not an AI-assisted diagnostic tool for human readers. Therefore, an MRMC study or "AI assistance" is not relevant to its performance evaluation.

    6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

    • Not applicable in the typical sense for an AI algorithm. The device is the "standalone" measurement tool. The "performance" being evaluated is the accuracy of the thermometer itself, not an algorithm's interpretation of data for human review.

    7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

    • For clinical thermometers, the ground truth is typically established by extremely accurate reference thermometers or highly controlled temperature environments calibrated against international standards. The document mentions "clinical bias, clinical uncertainty and clinical repeatability," which implies comparison against a reference standard, but the specific type of ground truth (e.g., calibrated reference thermometer readings) is not explicitly detailed.

    8. The sample size for the training set

    • Not applicable in the context of machine learning model training. This device is a hardware-based digital thermometer, not an AI model that undergoes training.

    9. How the ground truth for the training set was established

    • Not applicable as there is no "training set" in the context of an AI model for this device. The device's calibration and accuracy are established through engineering design, manufacturing processes, and testing against known temperature standards.

    Intended Use

    The ECG Holter evaluation software, MT-200, is an analysis software used for the analysis and evaluation of Holter ECG recordings. The Holter recordings are used for the diagnostics of symptomatic and asymptomatic arrhythmias, i.e. bradycardia, tachycardia, diagnostic of arrhythmias in patients with coronary artery disease, in patients after reanimation, in patients with different diseases such as cardiomyopathy, high blood pressure, long QT syndrome. A Holter ECG recording is also used for clarifying palpitations or syncopes and attacks of dizziness or for controlling medical therapies, or after operative treatments such as bypass operations or PTCA. The ST segment analysis of a Holter ECG is used for the detection of symptomatic or asymptomatic ischemias.

    AI/ML Overview

    Here's a breakdown of the acceptance criteria and study information for the SCHILLER Microvit MT-200 Holter Analyzer, based on the provided text:

    1. Table of Acceptance Criteria and Reported Device Performance

    CategoryAcceptance CriteriaReported Device Performance
    Arrhythmia DetectionBased on the procedures and limits described in ANSI/AAMI EC 38-1994 when compared to annotated classifications of AHA and MIT databases."All tests are passed." (Implying compliance with ANSI/AAMI EC 38-1994 limits).
    ST-T Segment AnalysisAbsolute difference between paired values (reader MT-200) is less than 0.1 mV. The total number of differences greater than 0.1 mV is less than or equal to 2% of the total number of measurements."All tests are passed." (Implying compliance with the 0.1 mV and 2% difference criteria).
    Software QualityConformity with "reviewer guidance for computer controlled medical devices undergoing 510(k) review"."All tests are passed."

    2. Sample Size Used for the Test Set and Data Provenance

    • Arrhythmia Detection: The test set comprised "the AHA and MIT data bases." No specific number of records or patients is provided, but these are well-known, publicly available databases widely used for Holter ECG algorithm validation. The provenance is likely mixed, given the international nature of these databases, and typically retrospective, as they are pre-recorded and annotated datasets.
    • ST-T Segment Analysis: The test set used "the ESC ST.T. database." Similar to the arrhythmia detection, no specific number of records is provided. This is also a well-known, typically retrospective database.

    3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

    • Arrhythmia Detection: The ground truth for arrhythmia detection was established by "the annotations in the databases [AHA and MIT]." The number and qualifications of experts who created these annotations are not specified in this document. These databases are generally annotated by multiple expert cardiologists or electrophysiologists.
    • ST-T Segment Analysis: The ground truth for ST-T analysis was established by "two independent observers." Their specific qualifications (e.g., "cardiologist with X years of experience") are not provided, only that they were "independent observers."

    4. Adjudication Method for the Test Set

    • Arrhythmia Detection & ST-T Segment Analysis: For arrhythmia detection, the MT-200's classifications were directly "compared with the annotated classifications of the data bases." For ST-T analysis, the MT-200's measurements were "compared to the deviations measured by two independent observers." This implies a direct comparison rather than an explicit arbitration or 2+1/3+1 adjudication method being used during the study. The ground truth itself, particularly for the well-established AHA/MIT/ESC databases, would have undergone rigorous expert consensus and adjudication during its creation.

    5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

    • No MRMC comparative effectiveness study is mentioned. The study focuses on evaluating the algorithm's performance against established ground truth rather than assessing human reader improvement with AI assistance.

    6. Standalone Performance

    • Yes, a standalone performance study was conducted. The document explicitly states: "The classifications given by the MT-200 were then compared with the annotated classifications of the data bases," and for ST-T analysis, "The STsegment deviations measured by the MT-200 were compared to the deviations measured by two independent observers." This demonstrates the algorithm's performance without human intervention in the loop during the reported tests.

    7. Type of Ground Truth Used

    • Arrhythmia Detection: Expert consensus, as represented by "the annotated classifications in the AHA and MIT databases."
    • ST-T Segment Analysis: Expert consensus, as determined by "two independent observers" measuring ST-segment deviations.

    8. Sample Size for the Training Set

    • The document does not provide any information about the sample size used for the training set. The study focuses solely on the evaluation of the device's performance using established test databases.

    9. How the Ground Truth for the Training Set Was Established

    • Since no information on a training set is provided, there is no mention of how its ground truth would have been established. This K973751 focuses on the validation of the developed software using known benchmark databases.
