Intended Use

The Page Writer 2001 Model 1770A is intended to provide acquisition, digitization and recording of couventional diagnostic 12 simultaneous lead ECG wavelorms and ECG Data, The Page Writer 200i Model M1770A also displays ECC waveforms and records patient information entered through the alphanimeric keyboard. Additionally, it measures and provides interpretation. The Page Writer 200i Model M1770A interpreted FCC7 with measurements and diagnostic statements is offered to the physician un an advisory basis only, and the physician is asked to overread and validate (or change) the ECG interpretation. In addition, the PageWriter 2001 Model M.1770A with ACI-TIPI Model M1791A is intended to provide the cardiologist with an additional tool to aid in assessment of acute cardiac ischemia.

Device Story

PageWriter 200i M1770A is an interpretive cardiograph; acquires/digitizes 12-lead ECG waveforms. ACI-TIPI M1791A is an optional software application; combines patient demographics (age, sex), chest pain status, and ECG measurements via regression formula. Output is a probability index (0-100%) of acute cardiac ischemia. Used in clinical settings by physicians; provides advisory diagnostic support. Physician must overread/validate all interpretations. Index serves as supplemental data; not for use in isolation or as a replacement for clinical judgment. Benefits include providing an additional tool for assessing acute cardiac ischemia.

Clinical Evidence

No clinical data. Bench testing and system validation performed to verify that the integration of the ACI-TIPI software application did not adversely affect the host cardiograph's interpretive functions.

Technological Characteristics

Interpretive cardiograph; 12-lead ECG acquisition; alphanumeric keyboard input. Software application (ACI-TIPI) uses regression formula for probability calculation. Connectivity via standard ECG recording techniques. System is a host cardiograph with optional software module.

Indications for Use

Indicated for patients requiring 12-lead ECG acquisition, recording, and interpretation. ACI-TIPI application is indicated for use by cardiologists as an aid in the assessment of acute cardiac ischemia by correlating patient demographics (age, sex), symptoms (chest pain status), and ECG measurements.

#### PREDICATE DEVICES 5.

The legally marketed devices to which equivalence is being claimed are listed below.

| Manufacturer | Predicate Device | Model | 510(k) Number |
|-----------------|------------------|-----------------------|---------------|
| Hewlett-Packard | PageWriter XLi | M1700A<br>with M1791A | K951978 |
| Hewlett-Packard | PageWriter 200i | M1770A | K935772 |

The interpretative cardiographic functions of the PageWriter 200i Model M1770A with ACI-TIPI Model M1791A are identical to the predicate PageWriter 200i Model M1770A (K935772). The optional software application, acute cardiac ischemia time insensitive instrument (ACI-TIPI) Model M1791A, is identical to the ACI-TIPI application that is commercially available for use with the predicate PageWriter XLi Model M1700A (K951978).

#### DEVICE DESCRIPTION 6.

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.

{3}------------------------------------------------

#### CONCLUSIONS FROM NONCLINICAL TESTING 10.

The addition of the ACI-TIPI Model M1791A application to the predicate PageWriter 200i Model M1770A interpretive cardiograph has been successfully completed and passed validation testing. In addition, system testing verified that the addition of the ACI-TIPI Model M1791A application does not affect the interpretive cardiograph functionalities of the host PageWriter 200i Model M1770A.
