The document describes an "interpretive ECG program" which performs "waveform rhythm and morphology" analysis and provides "diagnostic information on an advisory basis." While this involves analysis and interpretation, the document does not mention AI, ML, or any related terms, nor does it provide details about training or test sets which are typical for AI/ML-based systems. The description aligns with traditional algorithmic ECG interpretation rather than AI/ML.
No
The device is an electrocardiograph used for diagnosis and monitoring, not for treating a condition.
Yes
The device "prepares a record" and provides an "assessment of ECG waveform rhythm and morphology to assist the physician in diagnosis." It also offers "diagnostic information" to physicians on an advisory basis, which are all characteristics of a diagnostic device.
No
The device description explicitly states it is a "portable ECG acquisition terminal" that "measures up to 15 lead ECG waveforms" and includes hardware components like an "integral printer," "battery," "internal battery recharging circuit," and "AC power operation."
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body, such as blood, urine, or tissue, to provide information for diagnosis, monitoring, or screening.
- Device function: The Cardiofax V electrocardiograph processes electrical signals from the heart through electrodes placed on the patient's skin. It does not analyze specimens taken from the body.
- Intended Use: The intended use clearly states it processes electrical signals transmitted through electrodes to produce a patient record and assist in diagnosis based on these electrical signals.
Therefore, the device operates in vivo (within the living body) by measuring electrical activity, rather than in vitro (in glass/outside the body) by analyzing biological specimens.
N/A
Intended Use / Indications for Use
The Cardiofax V electrocardiograph is intended for medical purposes to process the electrical signals transmitted through two or more electrocardiograph electrodes to produce a patient record (monitor and recorder) and prepare a record and/or provide wireless transmission of data to a remote printer and/or computer.
For non-interpretive applications, the device is 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 and older. 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
Nihon Kohden's ECG-1500A series is intended for medical purposes to process the electrical signals produced by the heart through electrocardiograph electrodes and to produce a visual display, to produce a record and/or to transmit data to a remote computer. The product is a portable ECG acquisition terminal, which measures up to 15 lead ECG waveforms. The measured ECG waveforms are analyzed and a patient record is prepared for transfer to an ECG data filing system thru a wireless LAN or may be printed by integral printer with optional model available with recorder. Measurements and waveforms and diagnostic information are offered to physicians on an advisory basis.
The ECG-1500A series prepares a full page file with 3 to 15 channel selectable formats, waveform display and waveform analyses with measurements. The device includes keyboard data entry, battery with internal battery recharging circuit and AC power operation , all of which are features of the predicate devices. The new device offers an optional PC memory card, comparable to the predicate Nihon Kohden's ECGs. The new device does offer an external optional printer and uses a different type of battery. These changes have been made to address user preferences and do not affect the indication for use or safety and efficacy of the new device.

Trade Name: ECG-1500A series / Cardiofax V Common Name: Electrocardiograph or ECG Classification Name: The device has been classified as Class II by the Division of Cardiovascular Device Classification Panel under 21 CFR Part 870.2340 "Electrocardiograph" per 74LOS.
Nihon Kohden's ECG-1500A series is intended for medical purposes to process the electrical signals produced by the heart through electrocardiograph electrodes and to produce a visual display, to produce a record and/or to transmit data to a remote computer. The product is a portable ECG acquisition terminal, which measures up to 15 lead ECG waveforms. The measured ECG waveforms are analyzed and a patient record is prepared for transfer to an ECG data filing system thru a wireless LAN or may be printed by integral printer with optional model available with recorder. Measurements and waveforms and diagnostic information are offered to physicians on an advisory basis.
The ECG-1500A series prepares a full page file with 3 to 15 channel selectable formats, waveform display and waveform analyses with measurements. The device includes keyboard data entry, battery with internal battery recharging circuit and AC power operation , all of which are features of the predicate devices. The new device offers an optional PC memory card, comparable to the predicate Nihon Kohden's ECGs. The new device does offer an external optional printer and uses a different type of battery. These changes have been made to address user preferences and do not affect the indication for use or safety and efficacy of the new device.
The device complies with the IEC 60601-1 standard and sub-clause 56.3(c) implemented by 21 CFR Part 868 Performance Standard for Electrode Lead Wires and Patient Cables.
The device was subject to electromagnetic, environmental, safety and performance testing procedures. These tests verified the operation of the device. Software validation tested the operation of the software of the device. The results confirmed that the device performed within specifications.
Therefore based on the above. Nihon Kohden believes that the ECG-1500A series is substantially equivalent to our predicate devices.
