Intended Use
The DR512 digital Holter recorder is intended for the recording and storage of long-term ECG data collected from ambulatory patients. The recorder is used under the order of a physician, who reviews the data after downloading and processing by a Holter playback system. The physician determines the presence of normal and abnormal ECG data during the events of the patient's daily activity.
Device Description
The DR512 is a lightweight, compact, digital Holter recorder designed for ambulatory ECG applications. Three channels of ECG data are collected via a 5 or 7 lead wire set and silver-chloride electrodes. The recorder is battery powered to ensure electrical isolation of enclosure coated with an electromagnetic interference spray. The DR512 has internal calibration, and a patient activated event marker button. ECG data are collected for 24 hours.
More Information

Not Found

No
The description focuses on hardware and basic digital signal processing for data collection and storage, with no mention of AI/ML for analysis or interpretation.

No.
The device is a diagnostic tool that collects and stores ECG data for physician review, but it does not directly treat or alleviate a medical condition.

No

The device collects and stores ECG data for physician review, but the physician is responsible for determining the presence of normal and abnormal ECG data, indicating that the device itself does not perform the diagnostic analysis.

No

The device description explicitly details hardware components like lead wire sets, electrodes, a battery, and an enclosure. The performance studies also include verification and validation of analog and digital hardware.

Based on the provided information, the DR512 digital Holter recorder is an IVD (In Vitro Diagnostic) device.

Here's why:

  • Intended Use: The intended use clearly states that the device is for "recording and storage of long-term ECG data collected from ambulatory patients." This data is then reviewed by a physician to "determine the presence of normal and abnormal ECG data."
  • Nature of the Data: ECG data is physiological data collected from the patient's body. While the recording itself is external, the purpose is to analyze this internal physiological information to aid in diagnosis.
  • Role in Diagnosis: The physician uses the recorded ECG data to make a determination about the patient's health status (presence of normal or abnormal ECG data), which is a key step in the diagnostic process.
  • Comparison to Predicate Devices: The listed predicate devices (Datrix XR300 and Braemar DL700) are also Holter recorders, which are generally classified as IVD devices because they collect and store physiological data used for diagnosis.

While the device itself doesn't perform the in vitro analysis (that's done by the playback system and physician), it is an essential component in the process of collecting the in vitro diagnostic data (the ECG). Therefore, it falls under the scope of devices used in in vitro diagnostic procedures.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

The DR512 digital ECG Holter recorder has been tested and shown to conform to design specifications. Verification of the analog hardware was comprised of testing the ECG amplifier frequency response, amplification, and common mode rejection ratio, as well as the voltage converter, event button circuits, and battery polarity. Visual inspection of all parts was also made. A RAM write-read test of the digital hardware was conducted using an emulator to verify that the RAM was functioning, the RAM data, address, and control lines were connected correctly, and that the microcontroller was functioning. The recorder firmware was tested for flash disk control, A/D conversion and sampling rate, compression-decompression. The compression algorithms were tested with line segment data, calibration signals, and simulated ECG waveforms. The recorder was validated using both bench and subject testing. The recorder was also independently tested and shown to be compatible with commercially available playback systems.

Extensive troubleshooting was conducted to ensure that the recorder responded appropriately to improper use of the recorder. These tests included improper insertion of the flash card, improper termination of recording, improper insertion of the battery, and low battery. The beeps indicating proper functioning of the recorder were also tested.

Environmental tests were conducted to verify the operating ranges for temperature, humidity, and altitude. Shock and EMC testing were also conducted.

Results of all testing indicated that the DR512 digital Holter recorder is an accurate and consistent device, with repeatable performance. The recorder has been shown to perform to design specifications, and is suitable for ECG applications with ambulatory patients.

6. SUBSTANTIAL EQUIVALENCE

The DR512 is substantially equivalent to other commercially distributed ECG Holter recorders. The fundamental technical characteristics of the DR512 are similar to those of the predicate devices: all are 3-channel, record for 24 hours, and have similar standards and specifications. The main difference between the XR300 and the DR512 is the storage media. While the analog technology of the XR300 uses a cassette tape to store the data. both the DR512 and DL700 use digital flash disk technology. The technical characteristics of each recorder are summarized in the following chart.
