Intended Use
The ECG-9010K and ECG-9020K Cardiofax GEM electrocardiographs are intended for medical purposes to process the electrical signals transmitted through two or more electrocardiograph electrodes to produce a visual display and/or to prepare a record of the electrical signals produced by the heart. For non-interpretive applications, the ECG-9010K and ECG-9020K are intended for use with a full range of patient populations as determined by a clinician. The devices also provide an interpretive ECG program intended for use with patients age 3 years to adult. The interpretation program is intended to provide an assessment of ECG waveform rhythm and morphology to assist the physician in diagnosis. Assessments provided by the interpretation program are not intended as the sole basis for diagnosis. All assessments provided by the interpretation program are recommended for review by qualified physicians trained in electrocardiography.
Device Description
The ECG-9010K and ECG-9020K have been classified as Class III by the Division of Cardiovascular. Respiratory, and Neurological Devices and the Cardiovascular Device Classification Panel under 21 CFR Part 870.2340 "Electrocardiograph" as per 74 LOS. Common names for the ECG-9010K and ECG-9020K include ECG and electrocardiograph. Nihon Kohden's model ECG-9010K and ECG-9020K are intended for medical purposes to process the electrical signals transmitted through two or more electrocardiograph electrodes and to produce a visual display and/or prepare a record of the electrical signals produced by the heart. The ECG-9010K and ECG-9020K devices comply with the IEC 601-1 standard including subclause 56.3(c) implemented by 21 CFR Part 868 Performance Standard for Electrode Lead Wires and Patient Cables. To date, no other special controls or performance standards are known or established for these devices. The devices are also in compliance with the following voluntary industrial standards: IEC 601-2-25 and CSA 601-1. Defibrillator Discharge Protection: Class I, Type CF. The ECG-9010K and ECG-9020K are not intended to be sterile. The devices were determined to be non-contacting. Therefore, good laboratory practice studies were not required per 21 CFR part 58. The ECG-9010K and ECG-9020K were subjected to electromagnetic, environmental, safety and performance testing procedures. These tests verified the operation of the device. Software validation is performed to test the operation of the device software. The results confirm that the device performs within specifications.

No
The document describes an "interpretive ECG program" which provides an assessment of ECG waveform rhythm and morphology. While this involves analysis, the description does not mention AI, ML, or any related terms, and the testing described is standard performance and software validation, not AI/ML model training or testing.

No
The device is described as an electrocardiograph, which is used to record electrical signals of the heart for diagnosis, not to provide therapy.

Yes
The device is described as assisting the physician in diagnosis and providing an assessment, which are functions of a diagnostic device.

No

The device description explicitly states that the devices process electrical signals transmitted through electrodes and produce a visual display and/or record. This indicates the presence of hardware components (electrodes, display, recording mechanism) beyond just software.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD definition: In vitro diagnostics are tests performed on samples such as blood, urine, or tissue that have been taken from the human body to detect diseases or other conditions.
  • Device function: The ECG-9010K and ECG-9020K process electrical signals from the heart transmitted through electrodes placed on the body. This is a measurement of physiological activity in vivo (within the living body), not an analysis of a sample in vitro (outside the living body).
  • Intended Use: The intended use clearly states the device processes electrical signals transmitted through electrodes to produce a display or record of the heart's electrical signals. This is consistent with an electrocardiograph, which is an in vivo diagnostic tool.
  • Classification: The device is classified under 21 CFR Part 870.2340 "Electrocardiograph," which falls under the category of Cardiovascular Devices, not In Vitro Diagnostic Devices.

Therefore, the ECG-9010K and ECG-9020K are considered in vivo diagnostic devices, specifically electrocardiographs.

Name and Address of Applicant Nihon Kohden America, Inc. Attn: Regulatory Affairs 2601 Campus Drive Irvine, California 92612-1601 (949) 250-3959

The ECG-9010K and ECG-9020K have been classified as Class III by the Division of Cardiovascular. Respiratory, and Neurological Devices and the Cardiovascular Device Classification Panel under 21 CFR Part 870.2340 "Electrocardiograph" as per 74 LOS.

Common names for the ECG-9010K and ECG-9020K include ECG and electrocardiograph.

Nihon Kohden's model ECG-9010K and ECG-9020K are intended for medical purposes to process the electrical signals transmitted through two or more electrocardiograph electrodes and to produce a visual display and/or prepare a record of the electrical signals produced by the heart.

The ECG-9010K and ECG-9020K devices comply with the IEC 601-1 standard including subclause 56.3(c) implemented by 21 CFR Part 868 Performance Standard for Electrode Lead Wires and Patient Cables. To date, no other special controls or performance standards are known or established for these devices. The devices are also in compliance with the following voluntary industrial standards: IEC 601-2-25 and CSA 601-1. Defibrillator Discharge Protection: Class I, Type CF.

The ECG-9010K and ECG-9020K are not intended to be sterile.

The devices were determined to be non-contacting. Therefore, good laboratory practice studies were not required per 21 CFR part 58.

The ECG-9010K and ECG-9020K were subjected to electromagnetic, environmental, safety and performance testing procedures. These tests verified the operation of the device. Software validation is performed to test the operation of the device software. The results confirm that the device performs within specifications.

Therefore based on the above, Nihon Kohden believes that the ECG-9010K and ECG-9020K are substantially equivalent to the ECG-9320A.
