## Indications for Use
The VX3 digital Holter recorder is intended for the recording of ECG data collected from ambulatory patients. The recorder can collect data in the presence of implanted pacemaker pulses, and can detect and record the occurrence of signals characteristic of pacemaker pulses. 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 as well as pacemaker pulses during the events of the patient's daily activity.
## Device Story
VX3 is a compact, digital Holter recorder for ambulatory ECG monitoring. It captures ECG signals via leadwires; stores data on removable compact flashcards; supports 2 or 3-channel configurations. Features include an LCD for leadwire verification/status, optional keypad, and optional pacemaker pulse detection. Operated by patients in ambulatory settings under physician order; data is subsequently downloaded to a Holter playback system for physician review. Physician uses processed output to diagnose cardiac arrhythmias and evaluate pacemaker function. Benefits include continuous cardiac monitoring during daily activities to capture transient events.
## Clinical Evidence
No clinical data provided. Substantial equivalence is based on bench testing and comparison of technical specifications, including electrical performance (bandwidth, CMRR, input impedance), environmental testing (shock, temperature, humidity), and functional feature comparison.
## Technological Characteristics
Materials: ABS 94-V0 plastic enclosure. Sensing: ECG leadwire input, >5MΩ impedance, >60dB CMRR. Energy: 2 AA or one 9V battery. Dimensions: 4.46 x 2.75 x 1.02 inches. Connectivity: Removable compact flashcard for data transfer. Processing: 8 or 10-bit resolution, 128-512 samples/sec/channel. Bandwidth: 0.05Hz to 60Hz. Pacemaker detection: Optional signal detection.
## Regulatory Identification
A medical magnetic tape recorder is a device used to record and play back signals from, for example, physiological amplifiers, signal conditioners, or computers.

## Description
The VX3 is a lightweight, compact, digital Holter recorder designed for the recording of ECG data collected from ambulatory patients. A derivative of the Datrix DR512 digital Holter recorder, the VX3 has enhanced features, including an LCD to verify leadwire hookup and display recorder status and error messages, optional keypad for selection of various options, and optional pacemaker pulse detection. Various channel and lead configurations are accommodated by using the appropriate leadwire set without additional recorder reconfiguration. Data are recorded on industry standard compact flashcards for subsequent download and to a Holter playback system. Sampling rates are factory programmable to accommodate compatibility with various OEM Holter playback systems.
### Intended Use
The VX3 digital Holter recorder is intended for the recording of ECG data collected from ambulatory patients. The recorder can collect data in the presence of implanted pacemaker pulses, and can detect and record the occurrence of signals characteristic of pacemaker pulses. 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 as well as pacemaker pulses during the events of the patient's daily activity.

Dear Ms. Luhmann:
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.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Image /page/3/Picture/10 description: The image is a black and white circular logo for the U.S. Department of Health & Human Services. The logo features the department's name in a circular arrangement around a stylized eagle. The eagle is depicted with its wings spread, and its head facing to the left.

Page 2 – Ms. Lauren M. Luhmann
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050. This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at (301) 594-4646. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97). You may obtain other general information on your responsibilities under the Act from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number (800) 638-2041 or (301) 443-6597 or at its Internet address http://www.fda.gov/cdrh/dsma/dsmamain.html
