The document explicitly states "Mentions AI, DNN, or ML: Not Found" and does not describe any AI/ML-specific components or training/testing data sets.
No
The device is described as an ECG processing and analysis system that generates reports for review by a user to render a diagnosis. It is not intended to treat, mitigate, or cure a disease or condition, which are characteristics of a therapeutic device.
Yes
The "Intended Use / Indications for Use" states that the system is intended to "analyze and report symptomatic and asymptomatic cardiac events and continuous electrocardiogram information" and that "a final report is generated based on the beat information from the entire ECG recording." It further specifies that "The reports are provided for review by the intended user to render a diagnosis based on clinical judgment and experience." This clearly indicates its role in providing information for diagnostic purposes.
No
The device description explicitly states that the ZEUS System processes data from the "Zio XT or Zio AT Patch," which are hardware ECG monitoring devices. The software is part of a larger system that includes hardware for data acquisition.
Based on the provided information, the Zio ECG Utilization Service (ZEUS) System is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs analyze samples taken from the human body (like blood, urine, tissue). The ZEUS system analyzes electrocardiogram (ECG) data, which is a recording of electrical activity of the heart, not a sample taken from the body.
- The intended use is to analyze and report cardiac events and ECG information. This is a diagnostic tool that processes physiological signals, not a test performed on a biological specimen.
- The input modality is Electrocardiogram (ECG). This confirms it's dealing with electrical signals from the body, not biological samples.
Therefore, the ZEUS System falls under the category of a medical device that processes physiological data for diagnostic purposes, but it does not meet the definition of an In Vitro Diagnostic.

Intended Use / Indications for Use
The Zio ECG Utilization Service (ZEUS) System is intended to analyze and report symptomatic and asymptomatic cardiac events and continuous electrocardiogram information for long-term monitoring by Zio XT or Zio AT Patch, a final report is generated based on the beat information from the entire ECG recording. It is indicated for use on patients 18 years or older who may be asymptomatic or who may suffer from transient symptoms such as palpitations, shortness of breath, dizziness, light-headedness, pre-syncope, fatigue, or anxiety and patients who are asymptomatic. The reports are provided for review by the intended user to render a diagnosis based on clinical judgment and experience. It is not intended for use on critical care patients.

Dear Gabrielle Logan:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part
