The function of the device is the acquisition and transmission of the ECG signal in order to support diagnosis of the patient's conditions. HD+ is a wireless or USB (with appropriate option) ECG acquisition device, to be used primarily as common front-end for standard PC/tablet platforms (Windows/MAC OS/others), for resting ECG applications. The device implements wireless communication via Bluetooth wireless technology or wired with USB communication. With both connection modes, HD+ sends the data to the receiver device without performing any analysis or filtering. HD+ is not intended for monitoring or analysis of the cardiac function or to diagnose the patient's health condition. Display, print and analysis applications on the receiver device are separate products. HD+ is not able to permanently store the acquired data, therefore it does not work unless a connection has been established with a receiver application. Furthermore, HD+ does not collect any of the patient's sensitive data (patient's name, age, previous health conditions etc.). HD+ detects the QRS complexes and transmit the receiving device. The QRS detection function is intended for patients aged 12 years or older.

## 4. DEVICE DESCRIPTION
HD+12 and HD+15 are the new revisions of Cardioline's HD+ wireless acquisition module. The HD+ is a digital portable acquisition device which can acquire the electrocardiographic signal of 12 and 15 standard leads. Connected with a receiver via Bluetooth or USB (with the optional USB connector), the HD+ performs no analysis or filtering but sends acquired data to a host application where the User Interface is implemented. By default, the device includes a demo compatible software "HD+ Display" whose purpose is providing a UI for viewing the traces acquired by HD+. HD+ Display provides a simple UI, sufficient to configure the application to connect to an HD+ device via Bluetooth (the application automatically detects if an HD+ device is connected via USB and does not require additional configuration) and sufficient to display the ECG traces as received by HD+. HD+ Display does not provide any clinical functionality; therefore, it does not provide any capability to store, print or analyze the acquired ECG.
lt is the host (PC or Tablet separated by HD+) which performs the analysis. HD+ is not intended to control or analysis heart function and/or to diagnose the patient's health status. The analysis program on the host is a separate product not marketed with the HD+.
HD+ is a wireless acquisition device, to be primarily used as ECG front-end acquisition device for PC/tablet (Windows/MAC OS/Android/iOS/others) standard platforms for Resting ECG applications. Depending on performance/price ratio, HD+ could be also used with selected embedded electrocardiographs. HD+ allows the patient to be ambulatory.
{5}------------------------------------------------
HD+ uses a standard Bluetooth data transmission technology to transmit 12-lead and 15-lead ECG data over a proximity range, providing electrical insulation and freedom of movement for the patient. The device implements the wireless communication via Bluetooth wireless technology. The Bluetooth radio protocol is implemented by a dedicated module, FCC compliant. In order to support the data transmission speed of the application, the device implements the BLE 5 protocol with DLE (Data Length Extension) and 2M PHY (bandwidth up to 2 Mbit/s). The minimum specifications of the device connected to HD+ is BLE 4.2 to support the band required by acquisitions at 500 s/s. In order to operate at 1000 s/s, the connected device must be BLE 5.0 (or higher) and have a compatible 2M PHY radio (2 Mbit/s). Alternatively, in addition to Bluetooth connectivity described above, the HD+ has an optional USB interface that can be used to transmit data. The USB interface provides an electrical insulation offering two means of patient protection (2MPP), allowing HD+ to be connected to any IT equipment conforming to IEC 62368-1.
The HD+ function consists of acquiring and transmitting ECG signals for display processing ECG signals for the purpose of supporting the diagnosis of patient conditions. The device does not store nor does it associate patient identification data to the acquired signal, nor does it perform analysis on such signal. The HD+ is used solely for transmission of ECG signals from patient to a host analysis platform.
The HD+ transmits a continuous stream of ECG samples at a rate of 500 s/s or 1000 s/s, with a resolution of 0.817 uV/LSB or 2.495 uV/LSB, selectable by the calling application of the host analysis platform. The average required transmission throughput for sending 15 leads at 1000 s/s is approximately 155kbit/s, while to send 12 leads at 500 s/s the required throughput is approximately 54 kbit/s. BLE 5 2M PHY provides the bandwidth needed to support the maximum required throughput.
The BLE communication link ensures that data is either received correctly or not received at all. It is up to the host application to detect packet losses, handling the data gaps appropriately (e.g. by filling the stream with invalid dummy samples, signaling transmission errors etc...). This approach has been preferred over enabling the data retransmission (supported by the module) to reduce the data iitter and transmission delay.
HD+ uses standard 12 lead or 15 lead ECG cables to acquire the physiological signal from the patient. HD+ is light and compact, comfortable to wear, minimizing motion artifacts caused by traditional electrodes and patient cables.
HD+ offers full ECG acquisition - meeting the standards used in clinical and diagnostic applications (AAMI, ANSI, AHA, ACC). HD+ uses a LED indicator to comfortably monitor the link status (off when unit is powered down, blinking when unit is attempting to connect with the receiver, steady when unit is connected with the receiver). HD+ uses a programmable key to send macro commands to the receiving system (i.e. acquire and print an ECG). Low-power technology allows continuous usage of the device for more than 10 hours (from full battery charge).
The HD+ continuously transmits the acquired data to a computer platform where compatible software, a Host Application authorized by Cardioline, is installed that acts as its User Interface. As an example of such Host Application, the device includes a compatible demo Windows application "HD+ display" from Cardioline to visualize the ECG traces and check the functionality of the results of the analysis must always be validated by qualified, trained medical personnel and the HD+ is intended for use in a medical environment. HD+ is intended to be used on adult and all pediatric patients. The device must be handled with care by taking all the necessary precautions in order to prevent and avoid shocks, vibrations, heat sources, liquids and anything else that may damage it.

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.
Try it yourself
Head to the search page and work through a few of these AI/ML fuzzy searches to build intuition: perivascular fat on CT · aortic valve calcification opportunistic screening on noncontrast CT · breast cancer prediction on digital pathology slides · autism detection · gestational age prediction · a hearing aid that can also detect a pulse · foundation model based analysis of ECG · large language models · penetration test. Watch how the relevance scores, intended use, and AI Performance tables tell you when results stop being meaningful.
