## Indications for Use

The ST Review Station is intended to allow Physicians and/or Clinical personnel from ER, Cath Lab, ICU, and other related settings to retrospectively review/analyze stored ECG data. By being able review/analyze ECG trends, including ST segment measurements, Clinicians and/or Physicians have access to information to assist in their ability to detect changes in a patient’s physiological condition and therefore enabling them to respond accordingly to a patient’s medical needs.

## Device Story

ST Review Station functions as an adjunct to the ELI 100/STM Electrocardiograph; it receives stored ECG data and ST segment measurements from the ELI 100/STM. The device utilizes a PC-based operating system to provide graphical visualization of ECG trends, median beat ECGs, and HR trends. It enables clinicians in clinical settings (ER, ICU, Cath Lab) to perform retrospective analysis, including superimposition scanning and serial comparison of averaged ST complexes. The device produces 3D color images of ST segment changes across 12 leads and generates 8.5 x 11-inch printouts. By facilitating the review of entire monitoring sessions, the device assists healthcare providers in identifying physiological changes, supporting clinical decision-making, and improving patient care management.

## Clinical Evidence

Bench testing only. Verification and validation testing were performed to ensure the integrity of ECG data and ST segment measurements received and stored from the ELI 100/STM was maintained.

## Technological Characteristics

PC-based system; color monitor display; 12-lead ECG data input; software-based graphical visualization and storage; 8.5 x 11-inch printing capability. No specific materials or ASTM standards cited.

## Regulatory Identification

A medical cathode-ray tube display is a device designed primarily to display selected biological signals. This device often incorporates special display features unique to a specific biological signal.

## Predicate Devices

- ELI 100/STM ([K895232](/device/K895232.md))
- ST Central Station ([K922927](/device/K922927.md))

### New Device Description:

The ST Review Station is an adjunct to the ELI 100/STM Electrocardiograph (12-Lead Diagnostic Electrocardiograph) to provide rapidly responsive trend data originating from the ELI 100/STM Electrocardiograph and associated patient population. The ST Review Station utilizes a PC based operating system with specially developed software that provides for the means to graphically view and/or present the ECG data captured and stored by the ELI 100/STM (legally marketed predicate device – K895232), including ST segment measurements.

### Intended Use:

The ST Review Station is intended to allow Physicians and/or Clinical personnel from ER, Cath Lab, ICU, and other related settings to retrospectively review/analyze stored ECG data. By being able review/analyze ECG trends, including ST segment measurements, Clinicians and/or Physicians have access to information to assist in their ability to detect changes in a patient’s physiological condition and therefore enabling them to respond accordingly to a patient’s medical needs.

### Comparison to Predicate Devices:

See Attached Table (Attachment 1)

### Non-Clinical Performance Data:

To ensure that the ST Review Station did not alter the integrity of the ECG data and ST segment measurements received and stored from the ELI 100/STM, the ST Review Station was subjected to verification and validation practices appropriate to determine that it is safety and effective for its intended use.

### Performance Data Conclusion:

The verification and validation tests performed demonstrated that the ECG data and ST segment measurements received and stored by the ST Review Station maintained their integrity as obtained from the ELI 100/STM. Therefore, supporting the determination of substantial equivalence while demonstrating its safety and effectiveness.
