### 2. DEVICE NAME
| Proprietary Name: | DR300 Holter Monitor |
|----------------------|-------------------------------------------------------------------------------------------|
| Common/Usual Name: | Ambulatory ECG recorder, Ambulatory Electrocardiograph (without analysis), Holter Monitor |
| Classification: | Class 2, 21 CFR 870.2800 |
| Classification Name: | Ambulatory ECG recorder |
| Product Code: | MWJ |
#### 3. PREDICATE DEVICES
- K061293 Telaheart Digital Recorder / DR200 .
#### 4. DEVICE DESCRIPTION
The DR300 is an ambulatory monitor, sometimes called a Holter, which is a painless method to monitor the heart beat for a period of time (such as 24 hours, 48 hours, 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 Holter or digital recorder.
{4}------------------------------------------------
The DR300 Recorder has two modes that allow it to be used either as a standard Holter monitor or a looping Event recorder. The device is designed to facilitate ambulatory cardiac monitoring on the order of a physician, of those patients (including infants weighing less than 10 kg) who may benefit from such monitoring.
The data obtained during 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 or Event analysis system (TelePro Software) to be analyzed. The Holter Analysis Software was cleared by FDA under K930564.
The device is not intended to replace real time telemetry monitoring for patient suspected of having life threatening arrhythmias.
The DR300 Digital Recorder package includes:
- . DR300 Digital Recorder
- Operation Manual
- SD Card ●
- Patient Cable
The DR300 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.
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 DR300 digital recorder uses NorthEast Monitoring NorthEast Monitoring shielded patient cables with either 5 or 7 patient leads for a 3 channel recording or three leads for 2 channel Holter Recording.
The DR300 has an LCD that is used to display the time of day (during the recording), prompts and error messages (during the hookup procedure or during recording), or lead quality (during the hookup procedure).
The data collected by the DR300 digital recorder is stored on a removable SD Card.
The DR300 is packaged in a plastic bag in a cardboard shipping carton. The shipping carton will also include a patient cable and an SD Card.
{5}------------------------------------------------
The difference between the DR300 and the DR200/Telaheart is the wireless capability. The DR300 digital recorder is equipped with wireless Bluetooth transmitter. A NorthEast Monitoring Bluetooth Gateway or USB Dongle is able to receive the encrypted Holter and Event data.
In order for the wireless transmission to occur, the DR300 will need to come in range of a North East Monitoring transceiver - either a gateway or a PC with a USB Adapter. If there is sufficient data to send, the recorder will attempt to locate a transceiver every 20 minutes. When the transceiver is found the data will be sent. Transmission may be started manually by pressing the enter button.
### 5. INTENDED USE
The DR300 Digital Recorder can be used in Holter mode and Event Recorder mode.
### Holter Mode
Detection of Arrhythmias, Efficacy of Pharmacological Treatment, and Pacemaker Evaluation.
### Event Recorder
The DR300 event recorder module is a patient activated device designed to record and for diagnostic evaluation of transient symptoms (such as dizziness, palpitations, syncope, and chest pain). Once data is recorded, the data is transmitted wirelessly for evaluation.
#### 6. TECHNOLOGICAL CHARACTERISTICS AND SUBSTANTIAL EQUIVALENCE
The DR300 substantially equivalent to the Telaheart / DR 200 cleared under 510(k) K061293. The DR300 is equipped with a wireless Bluetooth transmitter and has additional shielding to be immune to radiofrequency interference and in order to pass FCC and EMC test requirements.
When the wireless function is enabled by the physician/technician, once every preset interval (normally set at 20 minutes) the device will check for the availability of any new data since the last successful transmission. If there is any, the Bluetooth module will be enabled and an attempt made to establish a link. If a link is established, then all available new ECG data will be transmitted. After each "block" of data is transmitted (normally 16 K bytes or less) a verification will be made for a successful transmission by the detection of a reply from the receiving end. The data will be re-transmitted if needed.

- Simulated bench and wireless testing (see summary below)
{7}------------------------------------------------
The testing included 11 Holter Tests for the purposes of verifying that the DR300 functions as intended. Testing was conducted related to the functionality of the Holter and Event functions of the DR300 without the wireless function being utilized. These tests verified that the device functions as intended after the inclusion of the Bluetooth transmitter and additional shielding. The testing ranged from monitoring over a 24 hour to 14 day period. Additional testing was performed to evaluate the wireless Bluetooth technology and communication of encrypted data. The wireless testing ranged from monitoring over a 24 hour to 48 hour period.
All testing confirmed that the device using the wireless technology functioned as intended and found no issues of safety or effectiveness.
## 9. CONCLUSION
North East Monitoring believes that based on the indications for use, technological characteristics, and comparison to predicate devices the DR300 has been shown to be substantially equivalent to the predicate.
Two short videos show you everything — or skip straight to the written tutorial if you'd rather read. You can reopen this any time from the Tutorial button in the top bar.
Part 1 — Search, results, and everyday workflows 16 min
Part 2 — Embeddings: the galaxy map 3 min
1. Search: exact and fuzzy
Type a phrase like "coronary artery calcification" into the search box. You get two kinds of results. Exact results match the literal phrase — prefix searches work ("coronary artery calcificati") but suffix searches do not. Fuzzy results match on the meaning and intent of your phrase rather than the exact words, and are sorted by relevance score. Hover over the Exact or Fuzzy badge on any row to see exactly why it matched.
Use the checkboxes above the results to narrow: SaMD keeps only software-only devices, AI / ML keeps only devices with AI.
Exact vs. fuzzy search: what's the difference?
Exact matches on the literal phrase (prefix search works, suffix does not). Fuzzy matches on the meaning and intent of the phrase rather than the exact words. Hover over the badge on any row to see why it matched.
You search "coronary artery calcification" and want only software devices with AI. What two filters do you apply?
Narrow by SaMD (software-only devices), then narrow by AI/ML (devices with AI).
2. The results table
Scroll right in the results table. The intended use is extracted for you — no need to open the PDF. The device story gives a high-level snapshot of what the device does and how it's used. The AI Performance sub-table shows each output name, acceptance criteria, observed values, and development/test dataset descriptions — the same format Innolitics uses for regulatory strategy outputs, and the fastest high-level fingerprint of an AI device. It is AI-generated but has been very reliable in practice.
Where do you find a device's intended use without opening the PDF?
Scroll right in the search results table. The intended use column is extracted for you; no need to dig into the 510(k) summary PDF.
What does the AI Performance sub-table show, and why is it useful?
Output name, acceptance criteria, observed values, development dataset description, and test dataset description. It's the same format we use for regulatory strategy output and Fast 510(k) input, and the fastest high-level fingerprint of an AI device. AI-generated but reliable in practice.
3. Judging fuzzy relevance
Fuzzy results trail off in relevance as you scroll. Use three signals to decide how far down to go: the fuzzy badge explanations, the intended use column, and whether your target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, you're past the relevant zone. A top hit with a low score (~0.4) and a stretched explanation is a hint the closest predicates are far away — the project may be headed for De Novo. Note the fuzzy search is a pattern match: it doesn't handle negation ("not") well, and hardware devices can appear — filter by SaMD/AI ML to cut them.
How do you judge how far down fuzzy search results to go?
Use the relevancy signals: the fuzzy badge explanations, the intended use column, and whether the target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, results are trailing off in relevancy.
4. Device detail page: chat and citations
Click a device name to open its detail page: device facts on the left, a chat window on the right. Ask something like "Describe the training data". The answer carries little citation bubbles — click one to jump to the highlighted passage in the source PDF, so you can verify every AI answer against the document. There's also a Download PDF button for sharing.
How do you verify an AI chat answer on the device detail page?
Click the citation bubbles to jump to the relevant highlight in the source document.
Reading rule for every project: how many summaries do you read in full?
At least the three most relevant 510(k) or De Novo summaries, in full. After that, use targeted chat questions to confirm your memory quickly. The tool supports this professional habit — it doesn't replace it.
5. Side-by-side comparison
Select multiple rows in the results table (aim for under ~10), then open the PDF Viewer tab. Ask one question — it goes to all selected devices in parallel, each with citations. This is the fastest way to compare and contrast devices: training data, PCCP scope, how they handled adding new scanners, and so on.
What does the side-by-side PDF viewer mode do?
Select multiple devices, open the PDF viewer tab, and ask one question (e.g., "Describe the training data"). It queries all selected devices simultaneously with citations, so you can compare and contrast quickly.
6. Collections
With rows selected, go to the Collections tab and create a labeled collection (e.g., "Cobb Angle Project"). Reload that selection any time — before a client call, pull up the collection and ask questions across all of its devices at once.
How do you save a set of selected devices for later use?
Select the rows, go to the Collections tab, and create a labeled collection (e.g., "Cobb Angle Project"). You can reload the selection anytime and carry it into the PDF viewer and other tabs that support selections.
7. Product codes and the regulations tree
Click a product code in the results to jump to it in the regulations tree — identification text, sibling product codes, and devices you can open in a PDF viewer on the right. Click a regulation number to see its identification, special controls, and related product codes. You can also search by product code or regulation number at the top of the tree. Always read the special controls if any exist for your device — it broadens your search and sharpens pre-kickoff research.
What can you do from the regulations tree view?
Browse product codes and regulation numbers, read the identification text and special controls, browse sibling product codes, open device PDFs on the right, and search by product code or regulation number at the top of the tree.
8. Chart view
Click Show Chart and segment by regulation number (or product code) to see which regulations dominate your result set. Clicking a regulation takes you into the regulations tree. Great for spotting that most matches are, say, hardware laparoscopic devices — a cue to go back and filter.
How do you see which regulations dominate a search result set?
Click "Show Chart" and segment by Regulation Number. Clicking a regulation takes you to the regulations tree.
9. The predicate graph
Open the Predicates tab for a family-tree view of predicate relationships. Click a node to trace its parents and children; selections from search carry over pre-selected. Commonly predicated devices are worth reading — a lot of people predicated them for a reason. The visual lineage is also handy on client calls, e.g. to show how a predicate family evolved and justify why your predicate still holds.
In the predicate graph, why are commonly predicated devices worth reading?
A lot of people predicated them for a reason. Clicking a node traces parents and children, and selections from search carry over pre-selected.
10. Embeddings: the galaxy map
The Embeddings tab plots every matching document in a 2-D "galaxy map" where semantically similar devices cluster together. Hover or click clusters to explore, and let AI label the clusters for you. Embeddings beat product codes for grouping: two devices can carry different product codes (LLZ vs. QIH) yet do the same thing — the embedding captures the meaning of the intended use and device story. This is also exactly how retrieval-augmented generation (RAG) works under the hood, and it makes a great visual on client calls.
