Intended Use

The MAC 7 Resting ECG Analysis System is intended to acquire, analyze, display, and record electrocardiographic information from adult or pediatric populations. Basic system simultaneously acquires data from each lead. Once the data is acquired, it can be analyzed, reviewed, stored, printed or transmitted. Transmission and reception of ECG data and other clinical data to and from a central clinical information system is optional. The MAC 7 Resting ECG Analysis System is intended to be used under the direct supervision of a licensed healthcare practitioner, by trained operators in a hospital, medical professional's facility or wherever ECG testing is performed.

Device Story

Mobile electrocardiograph; acquires, analyzes, displays, and records 3, 6, 12, or 15-lead ECG signals via surface electrodes. Operates in hospitals/clinics under physician supervision. Features include interpretive analysis (12SL v24), network connectivity (wired/WiFi) for integration with cardiology information systems (e.g., MUSE), and thermal printing. Device supports downloading prior ECGs for comparison, lead reversal detection (limb and chest), and configurable HD Pace detection. Output provides clinicians with diagnostic data to assist in clinical decision-making. Benefits include improved workflow efficiency and diagnostic support through automated analysis and historical data access.

Clinical Evidence

No clinical data. Substantial equivalence supported by bench testing, including risk analysis, design reviews, software development lifecycle, unit-level testing, system integration, performance verification, and safety testing.

Technological Characteristics

Mobile electrocardiograph with thermal dot array recorder. 10-inch LCD (1280x800). Connectivity via wired LAN or WiFi. Complies with ANSI/AAMI ES60601-1. Software-based interpretive analysis (12SL v24). Battery-powered (rechargeable/replaceable). Supports 3, 6, 12, or 15-lead acquisition.

Indications for Use

Indicated for non-invasive acquisition, analysis, display, and printing of ECGs in adult and pediatric (birth through 21 years) populations. Used in clinical settings by physicians or trained personnel under physician orders. Not intended as sole diagnostic means; requires physician over-read and consideration of other patient data. Contraindicated for patient transport, use with high-frequency surgical units, intra-cardiac applications, or as a vital signs monitor.

Regulatory Classification

Identification

An electrocardiograph is a device used to process the electrical signal transmitted through two or more electrocardiograph electrodes and to produce a visual display of the electrical signal produced by the heart.

Dear Yang Honghong:

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 (the 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 available 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.

## Predicate Device(s):
MAC 7 Resting ECG Analysis System (K203786)

## Reference Device:
MAC VU360 Resting ECG Analysis System (K173830) and Page Writer TC30 Cardiograph (K210560)

## Device Description:
The MAC 7 Resting ECG Analysis System is a mobile electrocardiograph designed to acquire, analyze, display, and record ECG signals from surface ECG electrodes.

The device can capture 3, 6, 12 or 15 lead electrocardiograms, provide interpretive analysis, and print reports.

The device can connect to a network, either through a wired LAN connection or via wireless WiFi access points. Once on the network, the device can optionally interface with cardiology information systems such as the GEHC MUSE® system to participate in a complete electrocardiology workflow.

The device provides state-of-the-art information technology security features and a contemporary user interface. Mobility is provided via an optional trolley.

## Intended Use:
The MAC 7 Resting ECG Analysis System is intended to acquire, analyze, display, and record electrocardiographic information from adult or pediatric populations. Basic system simultaneously acquires data from each lead. Once the data is acquired, it can be analyzed, reviewed, stored, printed or transmitted. Transmission and reception of ECG data and other clinical data to and from a central clinical information system is optional.

The MAC 7 Resting ECG Analysis System is intended to be used under the direct supervision of a licensed healthcare practitioner, by trained operators in a hospital, medical professional's facility or wherever ECG testing is performed.

## Technology:

The subject MAC 7 employs the same fundamental scientific technology, basic design, construction, materials, energy source, control mechanism, and operating principles as the predicate device MAC 7 in acquiring, analyzing, recording, displaying and printing ECG data for both adult and pediatric populations.

The basic system prints 3, 6 12 or 15 leads of ECG and provides optional transmission and reception of ECG data to and from a central ECG cardiovascular information system. The system can be upgraded with software options, such as communication options which is similar to the predicate device.

The subject MAC 7 Resting ECG Analysis System is similar to the predicate MAC 7 Resting ECG Analysis System (K203786), in the technology of downloading orders and patient demographics from a central ECG cardiovascular information system (e.g. MUSE) as well as supporting ECG reports in PDF. Both are able to use WiFi communication.

## Determination of Substantial Equivalence:

The MAC 7 Lite Resting ECG Analysis System is substantially equivalent to the primary predicate MAC 7 Resting ECG Analysis System (K203786) and reference MAC VU360(K173830)/TC30(K210560) as described in the following table:

| Prior ECG | Last ECG: Download to device, review on the screen and print from the cardiograph the most recent previous ECG from the same patient. | Prior ECG: Download to device, review on the screen and print from the thermal printer the most recent previous ECG from same patient. | Equivalent
The proposed MAC 7 V2 system includes a "Prior ECG" feature, which allows the user to download, review, and print the most recent previous ECG from the same patient using the device's screen and thermal printer. This functionality is equivalent to the "Last ECG" feature in the reference device, PHILIPS, TC30 (K173830).

The design of the Prior ECG feature uses current patient identification to query historical ECG data from the management system, enabling the retrieval and comparison of the most recent previous ECG with the current one from the same patient. The output of this process is consistent between the proposed and reference device. The only notable difference is in the labelling of the printed report, where MAC 7 V2 displays "Prior ECG" while TC30 uses "Previous ECG".

The labelling difference does not alter the functionality, or performance of the feature. Therefore, the addition of this feature does not impact the substantial equivalence of the proposed device. |
