However, the subject device is not intended for automated analysis and then arrhythmia classification algorithm being a part of Unified Arrhythmia Diagnostic System PocketECG IV (K193104) system should not be used to produce beat annotations to be considered during patient diagnosis.
Potential patient cardiac abnormalities, must be confirmed by a qualified ECG technician or by a physician with other relevant clinical information. The Q Patch does not provide interpretive statements.
The performance and integration tests were carried out to prove performance of Q Patch operation with Unified Arrhythmia Diagnostic System PocketECG IV (K193104).
The Q Patch is not intended for patients who should be hospitalized, patients with potentially life-threatening arrhythmias who require inpatient monitoring such as primary ventricular fibrillation or sustained ventricular tachycardia and for individuals where asystole represents the terminal rhythm of a cardiac arrest.
#### Indications for use V.
The Medicalgorithmics' Q Patch is intended to be used by patients who have a demonstrated need for extended cardiac monitoring and patients with symptoms that may be due to cardiac arrhythmias such as, dizziness, lightheadedness, shortness of breath, palpitations, dyspnea (shortness of breath), anxiety, syncope of unknown etiology in which arrhythmias are suspected or need to be excluded. It is indicated for use on adult patients. The sensor records single ECG channel for up to 15 days and can be used on patients with implanted pacemakers but is not intended to record pacemaker activity.
The Indications for Use statement for the Q Patch device is not identical to the predicate device; however, the differences do not alter the intended use nor do they affect the safety and effectiveness of the device relative to the predicate.
{7}------------------------------------------------
Image /page/7/Picture/1 description: The image shows the text "VI. Technological comparison to predicate device". The text is in black font and is left-aligned. The text is likely a heading or title for a document or section.
The intended use and technological features of the proposed Q Patch do not substantially differ from the legally marketed predicate device. Both devices are comprised of essentially identical configuration where the main component is a recorder. The operational characteristics are identical for the proposed and predicate device as they are both a small Holter recorders operated by professionals to acquire ECG data from a patient at a patient setting or wherever the patient may go. Both sensors are placed on the patient's sternum and record ECG signal continuously. The patient's ECG signal is managed similarly for both devices as it is recorded by the ECG recorder and at the end of recording can be downloaded through a USB port.
There are some differences between these two devices:
- The patient population indicated for the predicate device includes adults and ● all pediatric subgroups, whereas the pediatric use is restricted for the Q Patch. The subject device can be used in adults in the same way as the predicate device.
- The predicate device records ECG in 1 or 2 channel mode for up to 14 days or in 3 channel mode for up to 9 days. The subject device records ECG in one of these modes - single channel mode; for up to 15 days. Longer monitoring time is a minor difference and does not pose any additional risks and has no impact on the substantial equivalence of the product.
- The predicate sensor uses a rechargeable Li-Ion battery versus off the shelf, disposable, non-rechargeable lithium coin battery used in the subject device.
- When the recording is finished the ECG data stored in Q Patch's memory can ● be downloaded through a USB port using the Q Patch Downloader (PC application). While in the predicate device the patient's ECG is recorded to the device and then transferred via the USB data transfer cable to Holter analysis system (which is not a part of predicate's 510(k))
- . The subject device is also equipped with an additional application the Q Patch Mobile Application for interacting with the Q Patch recorder for transmission patient data to set up ECG recording session and displaying the Q Patch's status.
Differences between the predicate device and Q Patch are minor and have no impact on the substantial equivalence of the product. Descriptive characteristics and performance testing are used to demonstrate substantial equivalence. The 510(k) Premarket Notification demonstrates that the proposed Q Patch is substantially equivalent to the predicate device.

Image /page/10/Picture/0 description: The image shows the logo for Medical Algorithms. The logo has the word "MEDICAL" in gray and the word "ALGORITHMS" in red. Below the words is the phrase "INNOVATIVE SOLUTIONS IN MEDICINE" in gray.
### Performance tests
Tests which confirmed that the subject device, when used in conjunction with compatible electrodes, adequately adheres to the patient's skin throughout the wearing period were carried out. Study involving 18 participants, proved that the standard off-the-shelf Ag/AgCl electrodes when replaced regularly can be used with the Q Patch device to record ECG for up to 15 days.
Clinical study where ECG signals were recorded by the subject device and reference device simultaneously have been performed. The results of this analysis confirmed that there were no clinically significant differences in performance of the Q Patch against reference device. It has been demonstrated that non-standard ECG lead recorded by the Q Patch device is appropriate for ECG evaluation performed by the trained human interpreter. There were 30 participants involved in this study.
The subject device acquires ECG data and does not perform automatic arrhythmia analysis.
### Summary
Based on the performance study results the Q Patch system was found to have a safety and effectiveness profile that is similar to the predicate device and reference devices.
#### VIII. Conclusion
The Q Patch, type P5HP-AA-ADS is substantially equivalent to the predicate device as supported by the descriptive information and the performance testing. The verification and validation of hardware and software demonstrate that the Q Patch devices perform as intended in the specified use conditions. The performance data demonstrate that the Q Patch device performs comparably to the predicate device that is currently marketed for the same intended use.
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.
