Device Story

Software accessory for Nihon Kohden ECG-1500A/Cardiofax V electrocardiographs; processes electrical signals from electrodes during exercise stress testing (ergometer or treadmill). Performs automated recording, heart rate measurement, and ST-level calculation. Generates reports; stores data in internal memory, optional memory cards, or diskettes; supports data transfer to external instruments. Used by physicians in clinical/hospital settings. Output provides visual display and printed reports to assist in cardiac assessment and clinical decision-making.

Clinical Evidence

Bench testing only. Device underwent environmental testing (vibration, impact, drop), EMC testing (EMI, electrostatic, immunity, etc.), and safety testing (defibrillation protection, electrical separation, leakage current, etc.). No clinical data presented.

Technological Characteristics

Software-based exercise test option installed on ECG-1500A/Cardiofax V hardware. Features automated heart rate and ST-level measurement algorithms. Connectivity via memory card, diskette, or external instrument transfer. Non-sterile. Complies with safety standards for electrical separation, leakage current, and defibrillation protection.

Indications for Use

Indicated for patients requiring cardiac electrical signal processing and exercise stress testing. Used by physicians in hospitals, laboratories, clinics, or remote environments under physician supervision to monitor heart rate and ST levels during exercise.

Regulatory Classification

Identification

The QP-156E Exercise Test Option is an optional accessory for the Nihon Kohden ECG-1500A Series or Cardiofax V Electrocardiograph, per 510(k) K052511, commercial distribution certification dated May 24, 2006. 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 or usual Name: Electrocardiograph/ECG .
- Legally Marketed Predicate: Nihon Kohden OP-932E ECG Exercise Test . Option, 510(k): K972310 commercial distribution certification dated August 20, 1997 for ECG-9320A Cardiofax Electrocardiograph per 510(k) K961272 commercial distribution certification dated November 1, 1996.

Description and Intended Use: The QP-156E Exercise Test Option with its parent device, the Nihon Kohden ECG-1500A Series or Cardiofax V 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-156E will develop a report based upon acquired data and subsequent calculations. The ECG-1500A Series or Cardiofax V with OP-156E Exercise Test Option will be available for use by a physician within a hospital, laboratory, and clinic or in a remote environment under the supervision of a physician.

A summary of the technological characteristics of the device compared to the predicate device: The QP-156E exercise test software is installed into an ECG-1500A Series or Cardiofax V Electrocardiograph, it can manage exercise testing, perform auto recording and automatically measure heart rate and ST level. After exercise testing, QP-156E can also print a final report and save the examination data in the memory, or in an optional memory card or diskette, or transfer it to other external instruments. The product is similar to Nihon Kohden predicate device QP-932E Exercise Test Option and it provides setting items and protocol settings that can be changed in the system setting screen. You can use an ergometer and treadmill for exercise stress testing. See attachment # 5 for comparison of the QP-156E and QP-932E Exercise Test Options.

Performance Testing

- The device is not sterile. .
- The device was subject to environmental testing including vibration, impact and . drop test. EMC testing, including EMI, electrostatic, emission immunity, burst, conductive immunity, voltage dip, commercial frequency magnetic field and attachment document. Safety testing, including labeling, temperature rise, power input, protection against defibrillation discharge, electrical separation, ground resistance, humidity, withstanding voltage, leakage current, deflection, sharp edge, power interruption, creepage distance and air clearance were conducted. See Attachment 8.

There are no significant changes in function, performance or manufacturability compared to the predicate device that would affect the safety and effectiveness of the device as intended for use. Therefore, Nihon Kohden believes that the device is substantially equivalent to the predicate device.

Dear Mr. Coggan:

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.
