Cardiomatics
Cardiomatics is a CE/MDR-marked, cloud-based AI platform that analyses ambulatory Holter ECG recordings. Cardiac clinics, hospitals and general practitioners upload raw signals from more than 60 compatible recorders and download clinical reports entirely through a web browser.
What is Cardiomatics?
Cardiomatics is cloud-based ECG analysis software that automates the interpretation of ambulatory, or Holter, electrocardiogram recordings. The vendor presents it as medical grade software carrying CE/MDR marking, aimed at hospitals, cardiac clinics and outpatient practices rather than at consumers. It is published by Cardiomatics sp. z o.o., a Polish company based in Krakow whose managing director is named on the site.
The product rests on three pillars the vendor names explicitly: artificial intelligence, cloud infrastructure and interoperability. Its machine learning algorithms are described as having analysed over eight million hours of Holter ECG data and as learning from verified clinical cases. Nothing is installed: the platform runs entirely in a web browser, so a clinician logs in, uploads a raw Holter signal exported from a recorder, and downloads the resulting report. A public compatibility page lists twenty-seven recorder manufacturers by name, and the vendor claims support for more than sixty devices overall, with export instructions supplied per device.
Clinically, the software detects more than twenty arrhythmias and events, performs heart rate variability analysis, and presents findings in an interactive, editable viewer where the cardiologist verifies the report rather than accepting it blindly. Higher tiers add full disclosure of annotations, an ECG measurement tool, API and integration support, and reports carrying the customer's own branding.
The accuracy claim is backed by an independent comparison study run with University Hospital Basel, which reported a Pearson correlation of 0.998 against manual physician assessment for atrial fibrillation burden on seven-day recordings, and up to 2.5 hours saved per examination. Named customers report reductions of up to 80% in analysis time and 36% in patient waiting time for diagnosis. The vendor also points to a scientific board of four university professors and to a series of clinical studies across Switzerland, Poland, Germany, Croatia and the United States.
Commercially it is sold as a volume-based subscription across three tiers, with a free trial account available on request and no prices published anywhere on the site.

Cons
- No public pricing at all: neither amount, currency nor billing unit appears anywhere on the site
- Minimum monthly volumes of 10, 20 or 500 reports, on a one- or three-year commitment
- An API is sold as a line of the higher plan, but its documentation sits behind a login screen with nothing public
- No terms and conditions are published, so the actual contract cannot be read before making contact
- The site never states where data is hosted, naming neither a country nor a region
- No documented way to exclude your data from model training, and no published subprocessor register
- The ISO 27000 and ISO 27001 certificates quoted on the site belong to the cloud infrastructure, not to Cardiomatics itself
Pricing & Plans
There is no permanent free plan; the only free access is a trial account granted on request, during which patient data is not processed. No price is published on the site, in any currency: the three plans all lead to a sales conversation. The vendor describes two payment models, a volume-based subscription and a pre-paid package, with charging driven by credits indexed to recording length, one credit for up to 48 hours and up to four credits beyond seven days. The stated rule is that the higher the committed monthly volume and the longer the contract, the lower the price per report. Subscriptions run for one or three years, and unused credits carry over between months. No lowest price point can therefore be quoted.

Data, GDPR & hosting
A consolidated view of how Cardiomatics handles your data.
GDPR overview
GDPR implementation is documented in unusual detail for a company of this size. A dedicated information clause names the controller, its registered office and a data protection officer at dpo@cardiomatics.com, and enumerates the rights of access, rectification, erasure, restriction, portability and complaint to the Polish supervisory authority, alongside the rights to withdraw consent and to object. Identity is verified before rights are exercised. Transfers outside the European Economic Area are declared and rest on adequacy decisions or standard contractual clauses, with HubSpot, Inc. named as a United States recipient and a right to obtain a copy of transferred data. A GDPR badge appears on the homepage and the partner page describes a GDPR-compliant platform. A Data Processing Agreement is available and signable online.
Who owns the data?
Cardiomatics sp. z o.o., based in Krakow, identifies itself as the personal data controller. Its data protection officer is reachable at dpo@cardiomatics.com and by telephone. Customers frame the processing contractually through a Data Processing Agreement, signed online, with separate variants for distributors, for patient data inside and outside the European Economic Area, and for engagements without patient data. Personal data held in the database is encrypted so that only Cardiomatics, which holds the key, can read it. Detailed processing terms for the application account itself sit behind the customer portal rather than on the public site, so the full contractual allocation of rights is not readable before contact.
Reuse rights
The public pages do not publish general terms and conditions, so the reuse rights attached to uploaded recordings and generated reports cannot be read before signing. What the site does state is the purpose framework of the information clause: contract performance, direct marketing, defence of legal claims, statutory obligations and handling enquiries, each tied to an article of the GDPR. Reports remain retrievable by the customer for three years on the Core plan and without a stated limit on Plus. Whether customer recordings feed model training is never addressed: the vendor describes algorithms trained on over eight million hours of Holter data and learning from verified clinical cases, without saying where that material comes from, and documents no mechanism for excluding your data from training.
Data retention & training
Hosting summary
The site does not disclose where data is hosted. No hosting country or region is named, there is no trust or security page, and the privacy policy is silent on data location. The infrastructure is described only as a secure and compliant cloud infrastructure, and the 81 international security certificates cited alongside it, including ISO 27000 and ISO 27001, are attributed to that infrastructure rather than to Cardiomatics itself. What is actually declared concerns protection rather than jurisdiction. Login and data entry pages are protected in the transport layer by SSL. Personal data held in the database is encrypted so that only Cardiomatics, holding the key, can read it, and passwords are protected by a one-way hash function. Regular backups are made and software components are updated regularly. For website personal data, transfers outside the European Economic Area are declared and rest on adequacy decisions, standard contractual clauses or equivalent instruments, with HubSpot, Inc. in the United States named as a recipient. No equivalent statement covers the location of patient recordings processed by the platform, which remains an open question for buyers.
Things to keep in mind
Risks and trade-offs to weigh before adopting Cardiomatics.
- Automation bias: the report is produced by an algorithm and must be verified in the editable panel, not accepted as final
- Attribution trap: the 81 security certificates and the ISO 27000 and ISO 27001 references belong to the cloud infrastructure, not to Cardiomatics, which claims no ISO certification of its own
- Hosting location is never disclosed, which matters for patient data governance and should be asked about explicitly
- No documented opt-out from model training, and no published subprocessor register to audit
- The compatibility list carries an explicit warning that inclusion implies no partnership, certification or endorsement by the device manufacturers; distribution partners are likewise not part of the product
- No published terms and conditions means the commercial and liability terms are invisible until you engage with sales
- Deskilling risk: routine reliance on automated interpretation can erode the manual reading skills a department needs when the tool disagrees
Setup & Integrations
Technical difficulty
Low for access, moderate for integration. Nothing is installed: the platform runs entirely in a browser, and the vendor announces implementation in two hours after signature rather than months. The real prerequisite is hardware, not software. You need a compatible Holter recorder and the ability to export the raw signal in a supported digital format; export instructions are published device by device across twenty-seven listed manufacturers, and unlisted equipment can be assessed on request. Connecting the platform to hospital systems is a separate step, depending on API and integration support available only on the higher plan.

Should you pick Cardiomatics?
Cardiomatics occupies a narrow and well-defined position: it does not try to be a general cardiology suite, it automates the interpretation of ambulatory Holter ECG recordings and returns a report a cardiologist verifies. On that ground its evidence is stronger than most tools in this category can show. An independent comparison study with University Hospital Basel reported a 0.998 correlation against manual physician assessment for atrial fibrillation burden, named customers across France, Switzerland and Poland publish concrete time savings, and a scientific board of four university professors is identified. The CE/MDR marking and the TGA badge apply to the product itself, not to a partner.
The friction is commercial and informational rather than clinical. Nothing about price is public: no amount, no currency, no billing unit, only a credit mechanism and a rule that higher volumes and longer contracts lower the per-report price. Minimum monthly volumes and a one- or three-year commitment rule out very small practices. No terms and conditions are published, so the contract cannot be read before contact.
Two gaps deserve attention from any buyer with a compliance function. The site never states where data is hosted, and the impressive-sounding 81 international security certificates, including ISO 27000 and ISO 27001 are attributed by the vendor to its cloud infrastructure, not to Cardiomatics itself, which claims no ISO certification of its own. Nor is any mechanism documented for keeping your recordings out of model training.
For a cardiac clinic drowning in Holter backlog, with a compatible recorder and volume enough to clear the minimum, this is a serious candidate worth a trial. Ask about hosting location, training use and the API documentation before signing.
