No
The description mentions a "regression formula" and a "probability index" derived from combining patient data and ECG measurements. This indicates a statistical model, not necessarily AI/ML. There is no mention of training data, neural networks, or other common AI/ML terminology.
No.
The device is described as providing acquisition, digitization, and recording of ECG waveforms, displaying ECG waveforms, recording patient information, measuring and providing interpretation of ECGs, and providing an additional tool to aid in the assessment of acute cardiac ischemia. These functions are diagnostic or provide information for diagnosis, rather than directly treating or mitigating a disease or condition.
Yes
The device acquires, digitizes, and records diagnostic ECG waveforms and data, displays ECG waveforms, and measures and provides interpretation. Furthermore, it explicitly states it is intended to provide an "additional tool to aid in assessment of acute cardiac ischemia" and helps the physician "support their diagnosis".
No
The device description explicitly states that the ACI-TIPI Model M1791A is an "optional software application for the commercially available predicate PageWriter 200i M1770A interpretive cardiograph." This indicates that the software is an add-on to a hardware device (the cardiograph), not a standalone software-only medical device.
Based on the provided text, the Page Writer 2001 Model 1770A and the ACI-TIPI Model M1791A software are not IVDs (In Vitro Diagnostics).
Here's why:
- IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The description clearly states that the Page Writer 2001 acquires, digitizes, and records ECG waveforms and data. ECGs are electrical signals measured from the surface of the body, not from samples taken from the body.
- ACI-TIPI Function: The ACI-TIPI software uses patient data (age, sex, chest pain status) and measurements from the ECG to calculate a probability index. Again, this relies on data derived from the body's electrical activity, not from in vitro samples.
Therefore, the device and its associated software fall under the category of in vivo diagnostic devices, as they are used to diagnose conditions by measuring physiological signals directly from the living body.

Device Description
The ACI-TIPI Model M1791A is an optional software application for the commercially available predicate PageWriter 200i M1770A interpretive · cardiograph. This optional software application is used to provide the cardiologist with an additional tool to aid in the assessment of acute cardiac ischemia. The ACI-TIPI application regression formula for ACI combines patient data (age, sex, and chest pain status) with measurements from the ECG. The computation yields a probability index of acute cardiac ischemia in the range of 0-100%. This index is intended to be used with the currently established data in evaluation of the subject patient population. As an index, the physician can correlate values with their current diagnostic results and then use the index to support their diagnosis, or to initiate further action. For example, the physician can use the index as part of the diagnostic data set used to assess a patient. This index is never used alone or in place of other pertinent information normally used in acute ischemia determinations.

7. INTENDED USE
The intended use of the PageWriter 200i Model M1770A with ACI-TIPI Model M1791A is similar to the intended use of the predicate PageWriter 200i Model
2
They are both intended to be used for acquisition, digitization, M1770A. recording of conventional diagnostic 12 simultaneous lead ECG waveforms and ECG data, and measuring and interpreting ECGs. In addition, the PageWriter 200i Model M1770A with ACI-TIPI Model M1791A has the same intended use as the predicate PageWriter XLi Model M1700A with ACI-TIPI Model M1791A. Specifically, they both are intended to provide a tool to aid in assessment of acute cardiac ischemia by correlation of the patient demographics, symptoms and ECG measurements.
COMPARISON OF TECHNOLOGICAL CHARACTERISTICS 8.
The PageWriter 200i Model M1770A with ACI-TIPI Model M1791A has the same interpretive cardiograph characteristics as the predicate PageWriter 200i Model M1770A. For example, they both contain the same ECG measurements, adult and pediatric analysis programs, ECG basic controls, conventional 12 simultaneous lead ECGs and both have the same recording techniques. The PageWriter 2001 Model M1770A with ACI-TIPI Model M1791A has the same predictive algorithm characteristics as the predicate PageWriter XLi Model M1700A with ACI-TIPI Model M1791A. In fact, the exact same ACI-TIPI Model M1791A application is used with both interpretive cardiographs. In addition, the same parameters are entered by the user (patient ID, name, age, gender, height, weight and presence of chest pain) and the same input parameters are needed for the predictive algorithm (ACI-TIPI).
NONCLINICAL TESTS USED IN DETERMINATION OF SUBSTANTIAL EQUIVALENCE 9.
The safety of the PageWriter 200i Model M1770A with ACI-TIPI Model M1791 A is already proven because the interpretive cardiograph which will host the ACI-TIPI algorithm is commercially available for market worldwide. In addition, the ACI-TIPI Model M1791A application is also commercially available on another Hewlett-Packard interpretive cardiograph. The ACI-TIPI Model M1791A application has been validated and system testing was performed to verify that the addition of the ACI-TIPI Model M1791A application did not adversely alter the functionality of the PageWriter 200i Model M1770A interpretive cardiograph.
