The document explicitly states "Not Found" for mentions of AI, DNN, or ML, and the description focuses on standard ECG signal processing and calculations.
No.
The device is used for diagnostic purposes by processing and displaying electrical signals from the heart, not for treating any condition.
Yes
Explanation: The device processes electrical signals from the heart to produce a visual display and record, which are used to assess the heart's electrical activity. This information is used by a physician to understand the patient's condition, which is a diagnostic purpose.
No
The device is described as an "optional accessory" for a physical electrocardiograph device (Nihon Kohden Cardiofax, Model ECG-9320A). While it performs software functions (processing signals, developing reports), it is explicitly tied to and dependent on the hardware of the parent device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device processes electrical signals from electrodes placed on the body to produce a visual display and record of the heart's electrical activity. This is a direct measurement of physiological signals from the patient, not an analysis of samples taken from the body (like blood, urine, or tissue).
- Device Description: The description reinforces that it's an accessory for an electrocardiograph, which is a device used for in-vivo measurement.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples, reagents, or any of the typical components associated with in vitro diagnostics.
Therefore, the QP-932E Exercise Test Option, in conjunction with the parent device, is an in-vivo diagnostic device used for electrocardiography during exercise testing.
N/A
Intended Use / Indications for Use
The QP-932E Exercise Test Option with its parent device, the Nihon Kohden Cardiofax ECG-9920A Electrocardiograph, is intended for medical purposes used to process the electrical signals transmitted through two or more electrocardiograph electrodes to produce a visual display and to prepare a record of the electrical signals produced by the heart. The QP-932E will develop a report based upon acquired data and subsequent calculations.

The QP-932E Exercise Test Option is an optional accessory for the Nihon Kohden Cardiofax, Model ECG-9320A Electrocardiograph, per 510(k) #K961272, commercial distribution certification dated November 1, 1996. The device has been classified as Class II by the Division of Cardiovascular, Respiratory, and Neurological Devices and the Cardiovascular Device Classification Panel under 21 CFR Part 870.2340 "Electrocardiograph" as per part 74 DPS.
Common names for the ECG-9320A Cardiofax device with the QP-932E Exercise Test Option include Electrocardiograph and Cardiograph.
The predicate devices are the Nihon Kohden Cardiofax, Model ECG-8340A Electrocardiograph per 510/k) #K865032. commercial distribution certification dated March 10, 1987 and the Quinton Instrument Company Model Q710 Exercise and Resting ECG System per 510(k) #K945626, commercial distribution certification dated June 28, 1995.
The QP-932E Exercise Test Option with its parent device, the Nihon Kohden Cardiofax ECG-9320A Electrocardiograph, is intended for medical purposes the electrical signals transmitted through two or more electrocardiograph electrodes to produce a visual display and to prepare a record of the electrical signals produced by the heart. The QP-932E will develop a report based upon acquired data and subsequent calculations. The ECG-9320A with QP-932E Exercise Test Option will be available for use by a physician within a hospital, laboratory, clinic or in a remote environment under the supervision of a physician.
To date, no performance standards or special controls are known or established for this device as required by Section 514 of the Food, Drug and Cosmetic Act and implemented by 21 CFR part 861.
The device is not intended to be sterile.
The Nihon Kohden Cardiofax ECG-9320A Electrocardiograph was subject to electromagnetic, environmental, safety and performance testing. These tests verified the operation of the device.
Software validation tested the operation of the software functions of the results confirmed that the device performed within specifications.
Therefore based on the above, Nihon Kohden believes that the QP-932E Exercise Test Option for the ECG-9320A Cardiofax Electrocardiograph is substantially equivalent to the Nihon Kohden Cardiofax, Model ECG-8340A Electrocardiograph and the Quinton Instrument Company Model Q710 Exercise and Resting ECG System.
