#### Submitter's Information [21 CFR 807.92(a)(1)]
Joseph M. Azary C/o NorthEast Monitoring Inc. 543 Long Hill Avenue Shelton, CT. 06484
Azary Technologies has received authorization to submit this 510(k) on behalf of the sponsor NorthEast Monitoring Inc. NorthEast Monitoring Inc. located at Two Clock Tower Place, Suite 360, Maynard, MA 01754, is an FDA-registered medical device under establishment# 1224919.
#### Trade Name, Common Name, Classification [21 CFR 807.92(2)(2)]
Device trade names are: NorthEast Monitoring SD360 Digital Recorder, SD360 Digital Holter Recorder Common Name: Ambulatory ECG Recorder, Ambulatory Electrocardiograph (without analysis) Classification: Class II, 21 CFR 870.2800, MWJ
#### Predicate Device |21 CFR 807.92(a)(3)|
- NorthEast Monitoring DR180 II Holter Recorder K001288 .
The subject device has the same indications for use as the predicate. Both the subject device and predicate device can be used for 3 channel recording. The main differences between the subject device and predicate device are as follows:
- . The subject device is smaller and thinner.
- The subject device weighs less. .
- The subject device requires only one AA battery (as opposed to two AA batteries required by the . predicate).
- . The subject device does not have 12 lead capabilities (this was not a heavily used option in the predicate device).
- . The LCD screen in the subject device is smaller. The LCD screen of predicate device showed waveforms, whereas the LCD screen of the subject device shows lead quality as a numeric value.
- The subject device uses SD cards instead of flash cards for memory. The SD cards are smaller, but . have the same memory capabilities as the flash cards.

#### Description of the Device [21 CFR 807.92(a)(4)]
An ambulatory monitor, sometimes called a Holter, is a painless method to monitor the heart beat for a All anloulatory moments, osmethics or 72 hours). The Holter is a small recording device that records the heart beat while being worn by the patient.
The physician or technician places electrodes and wires on the patient. The wires are connected to the I he prysicial or connectar patient is asked to write down a diary of daily activity including the time and character of any symptoms.
The patient can push a patient event button to mark an event. The patient must write down details about the event in their diary so that physician or technician can relate the event to specific symptoms or activities !
The NorthEast Monitoring SD360 Digital Recorder is a holter monitor designed to facilitate the ambulatory cardiac monitoring, on the order of a physician, of those patients who may benefit from such monitoring including but not limited to those with complaints of palpitations, syncope, chest pains, shortness of breath, or those who need to be monitored to judge their current cardiac function, such as patients who have recently received pacemakers.
The SD360 Digital Recorder package includes:
- . SD360 Digital Recorder
- . Operation Manual
- SD Card .
- Patient Cable
- Pouch ●
The data obtained by monitoring is not analyzed at the time of recording. After the recording is complete, the data must later be downloaded to a compatible NorthEast Monitoring holter analysis system to be analyzed. The Holter Analysis Software was cleared by FDA under K930564.
The SD360 is not intended to replace real time telemetry monitoring for patients suspected of having life-threatening arrhythmias.
The SD360 digital recorder is powered by one 1.5 volt AA alkaline battery (MN1500 or the equivalent), one AA rechargeable NiMH (nickel metal hydride) battery, or one AA Eveready Lithium L91 battery. Batteries should not be re-used for a second patient. The batteries are not included; users are instructed to purchase 2 AA batteries.
{2}------------------------------------------------
The device is compatible with standard silver / silver chloride ECG electrodes. Electrodes are not provided with the subject device. The user is instructed to purchase standard silver / silver chloride ECG electrodes.
The SD360 digital recorder uses NorthEast Monitoring SD360 patient cables with either seven leads or five leads for a 3-channel holter recording. The patient cable connects to the recorder via a 9-pin female connector on the recorder. A patient cable is provided with the SD360 Digital Recorder.
The SD360 has a small LCD that is used to display either time of day (during the recording), error messages (during the hookup procedure or during recording), or lead quality (during the hookup procedure).
The data collected by the SD360 digital recorder is stored on a removable SD Card. To store 24 hours in normal mode, the minimum capacity of the SD Card should be 28 megabytes; 56 megabytes are required for 24 hours in high resolution mode. To store 24 hours in 360 samples/sec mode, 112 megabytes are required. To stored 24 hours in 720 samples/sec, 224 megabytes are required. Double all storage requirements for 48 hour recordings, and triple them for 72 hour recordings. The SD360 is provided with an SD memory card with at least 32 megabytes.
The SD360 is packaged in a plastic bag in a cardboard shipping carton. The shipping carton will also include a patient cable and a pouch. The pouch is used by the patient to hold the digital recorder while in use.
The physician or technician can optionally use a PC as an interface to key in patient information. If a PC were used, the patient information would be keyed into the SD card using the NorthEast Monitoring Holter Analysis software (cleared under a separate 510k).
Another option for entering patient information is through the use of a PDA (i.e. Palm Pilot). Patient information such as patient name, sex, date of birth, identification number, scan number, hookup tech name or initials, physician name, indications, and medications.
