## Indications for Use

EASI ECG is intended for monitoring multiple leads of ECG of adults, pediatrics and neonates. ST. Segment monitoring is restricted to adult patients only.

## Device Story

EASI ECG is a lead switching adapter for electrocardiographs; it processes ECG signals to derive multiple leads from specific electrode placements. Operated by healthcare professionals in clinical settings, the device provides continuous ECG monitoring. It transforms raw electrode inputs into derived ECG leads, enabling arrhythmia detection and ST segment analysis (adults only). The output is displayed on a patient monitor, allowing clinicians to assess cardiac rhythm, evaluate therapy efficacy, monitor pacemaker function, and screen for ischemic heart disease. This facilitates clinical decision-making regarding patient treatment and symptom management.

## Clinical Evidence

Bench testing only. Performance was verified using a 1185-patient database. Results were compared against the predicate device and direct ECG measurements. The device met all pre-defined pass/fail criteria based on predicate specifications, demonstrating substantial equivalence.

## Technological Characteristics

Lead switching adapter for electrocardiographs (Class II, 21 CFR 870.2350). Uses specific electrode placements to derive multiple ECG leads. Software-based algorithm for signal processing and lead derivation. Designed for integration with Philips patient monitoring systems.

## Regulatory Identification

An electrocardiograph lead switching adaptor is a passive switching device to which electrocardiograph limb and chest leads may be attached. This device is used to connect various combinations of limb and chest leads to the output terminals in order to create standard lead combinations such as leads I, II, and III.

## Predicate Devices

- EASI Algorithm ([K020456](/device/K020456.md))
- Philips patient monitors ([K990476](/device/K990476.md))
- Philips patient monitors ([K032858](/device/K032858.md))

## 510 (k) Summary 9.0

summary of 510(k) safety and effectiveness information is This submitted in accordance with the requirements of the Safe Medical Devices Act of 1990 and 21 C.F.R. §807.92.

1. The submitter of this premarket notification is:

Philips Medical Systems

This summary was prepared on November 5, 2003.

- 2. The name of this device is the EASI ECG. Classification names are as follows:

| Classification | ProCode | Description                                    |
|----------------|---------|------------------------------------------------|
| 870.2350, II   | 74 DRW  | Adapter, Lead Switching,<br>electrocardiograph |

- 3. The new device is substantially equivalent to the previously cleared EASI Algorithm cleared under K020456 and Philips patient monitors cleared under K990476 & K032858.
- 4. The modification is a change that provides additional derived leads, alternative electrode placements, and an expanded patient population.
- 5. EASI ECG is indicated for use by health care professionals whenever there is a need to monitor ECG of adult, pediatric, or neonatal patients including arrhythmia monitoring or ST seqment changes of adult patients, to qain information for treatment, to monitor adequacy of treatment, or to exclude causes of symptoms.
- 6. The new device has the same technological characteristics as the legally marketed predicate device.
- 7. Verification, validation, and testing activities establish the performance, functionality, and reliability characteristics of the new device with respect to the predicate. Testing involved performance verification to a 1185 patient database and comparison of results to the predicate and direct ECG. Pass/Fail criteria were based on the specifications cleared for the predicate device and test results showed substantial equivalence. The results demonstrate that EASI ECG meets all requirements and performance claims.

Trade Namc: EASI ECG Regulation Number: 21 CFR 870.2350 Regulation Name: Electrocardiograph Lead Switching Adaptor Regulatory Class: Class II (two) Product Code: DRW Dated: November 5, 2003 Received: November 6, 2003

Dear Mr. Osborn:

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. 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.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such 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, I'DA may publish further announcements concerning your device in the Federal Register.
