TeltoHeart
TeltoHeart is a CE-marked medical wristband that records a six-lead ECG at the wrist, automatically flags atrial fibrillation, and syncs each reading to the TeltoCare platform so a clinician can review three months of history remotely.
What is TeltoHeart?
TeltoHeart is a medical-grade heart monitoring wristband built by UAB TELTONIKA TELEMEDIC, the health arm of the Lithuanian Teltonika group. It is deliberately not a wellness tracker: it carries CE MDR Class IIa medical device certification, awarded in May 2024, and is sold as a clinical instrument you happen to wear all day.
The product is really three pieces working together. The wristband carries two sensors on the front and four on the back, arranged so that three physical electrodes form Einthoven's triangle. From those contact points it records leads I, II and III and derives aVR, aVL and aVF, producing a six-lead electrocardiogram where most smartwatches capture a single lead and therefore a single view of the heart's electrical activity. Between recordings it tracks heart rate continuously using photoplethysmography, along with blood oxygen saturation and step count. The device is rated IP67 against dust and water and is designed for continuous everyday wear.
The second piece is the TeltoHeart mobile application, available for iPhone and Android in seventeen interface languages. It pairs with the wristband and forwards recordings onward. The third is TeltoCare, a web platform where the wearer reviews their own data and, with explicit consent, opens the last three months of history to a healthcare provider.
What underpins the clinical claim is an algorithm developed with Kaunas University of Technology and Vilnius University Hospital. The vendor states 94.2% accuracy for atrial fibrillation detection in everyday conditions and points to two peer-reviewed papers in Frontiers in Cardiovascular Medicine: one from 2022 on combining photoplethysmography with six-lead ECG for atrial fibrillation detection, one from 2023 comparing six-lead and single-lead recordings.
Eleven Lithuanian clinics in Vilnius, Kaunas and Klaipeda are listed as TeltoCare users, in person or remotely. Where a provider does not use the platform, the wearer can export a health report or show the data on screen during an appointment.
The wristband sells for 100.00 EUR as a one-time purchase in three bracelet sizes, with a 24-month warranty. The terms set a minimum age of 22, exclude emergency use and self-diagnosis, and state plainly that the device does not replace a healthcare professional.
What it does
- Record a six-lead electrocardiogram from the wrist, on demand or when symptoms appear
- Automatically detect atrial fibrillation and other heart rhythm irregularities
- Track heart rate continuously through photoplethysmography, plus SpO2 and step count
- Sync every recording to the TeltoCare platform through the mobile app
- Open three months of heart history to a healthcare provider, with explicit consent
- Generate and export a health report for a doctor who does not use TeltoCare
- Grant an authorised relative access to monitor an elderly or dependent wearer
When to use TeltoHeart / When not to
A quick filter to help you decide if TeltoHeart is the right fit.
When to use TeltoHeart
- People who feel palpitations, dizziness or unexplained fatigue that never show up during a short surgery visit
- Patients already diagnosed with an arrhythmia whose treatment needs to be checked against continuous, real-world heart data
- Cardiologists and general practitioners working with the TeltoCare platform, who gain three months of ECG history before a consultation
- Families monitoring an elderly or dependent relative remotely through an authorised account
- Active adults and athletes who want a medical-grade recording of what their heart does during sleep, work and exercise
When not to use TeltoHeart
- Anyone facing a medical emergency: the terms exclude emergency use outright and tell you to call a doctor or emergency services
- Users under 22, who are contractually barred from using the product
- People looking for a self-diagnosis tool: the vendor states the device is not intended to diagnose, cure or prevent disease on its own
- Developers or hospital IT teams wanting to pipe readings into another system, since no API or developer documentation exists
- Buyers who want to test before committing, as there is no free trial and no free plan, only a 30-day return
How to use TeltoHeart
A typical end-to-end flow, from setup to results.
- Order the wristband from the online shop, choosing a bracelet size between Small (10-15 cm), Medium (15-20 cm) and Large (20-25 cm)

- During registration, select one of the healthcare providers that use TeltoCare if you want a clinician involved
- Pair the wristband with the phone over Bluetooth and let the app synchronise readings automatically
- Wear the device day to day so that heart activity is monitored continuously and ECGs are recorded
- Trigger a full or partial ECG recording yourself whenever symptoms appear
- Give your consent so the chosen provider can access the last three months of heart data
- Review or discuss the recordings with your clinician before or during a consultation
- If your provider does not use TeltoCare, export a health report from the platform or show the data on screen during the appointment
Pros & Cons

Data, GDPR & hosting
A consolidated view of how TeltoHeart handles your data.
GDPR overview
GDPR implementation is concrete and documented. The TeltoHeart Privacy Policy, last updated 23 August 2023, names its legal bases (contract performance, legitimate interest, legal obligation, consent) and lists the full set of data subject rights, with a one-month response deadline extendable by two months. Transfers outside the EEA rely on the European Commission's standard contractual clauses under Article 46(2)(c) GDPR, and the group's published Data Processing Agreement adds the EU-U.S. Data Privacy Framework where applicable, names every sub-processor in Annex C, and gives customers advance notice plus a five-day right to object to changes. A Data Protection Officer can be reached at privacy@teltonika.lt. No Article 27 representative is designated, and none is required: the company is established in Lithuania.
Who owns the data?
UAB TELTONIKA TELEMEDIC is the controller for data collected through the wristband, the mobile app and the TeltoCare platform, and it keeps ownership of the software: users receive only a limited, non-exclusive, non-transferable and revocable licence, and all product content and trademarks remain the vendor's. The personal data itself stays the wearer's, with rights of access, rectification, erasure, restriction, objection, portability and withdrawal of consent. The picture flips when the wristband reaches you through a clinic: the vendor then acts as a processor, the provider's own privacy statement applies instead, and data subject requests must be addressed to that provider rather than to Teltonika.
Reuse rights
Wearers may reuse their own health data freely and without asking permission. TeltoCare lets them generate and save a health report, share it by email or any other method agreed with their doctor, or simply display it on screen during a consultation. What cannot be reused is the product itself: the terms forbid copying, republishing, reverse engineering, redistributing or scraping any software, content, trademark or interface element, and reserve all rights not expressly granted. On the vendor's side, data serves account creation, service delivery, product development, marketing, investigations, legal compliance, automated processing and system improvement, and may be shared with service providers, group companies, competent authorities, external auditors, advertising partners and, in aggregated non-identifying form, with academic institutions for research.
Data retention & training
Hosting summary
The group's Data Processing Agreement states in Article 6.1 that customer data is transferred, stored and processed in Lithuania, or in any other country where the vendor or its sub-processors operate. The TeltoHeart Privacy Policy adds that the company and the independent controllers it works with are usually located in European Union member states and store data in EU countries. Annex C of the Data Processing Agreement names each sub-processor with its location: Amazon Web Services EMEA (Europe, hosting infrastructure), Google (Europe, marketing, analytics and Firebase messaging), Sentry (Europe, error tracking), Kibana (Europe, log visualisation), MailerLite (Europe, service emails), NextCloud (Europe, support file storage) and CloudTalk in the United States. Transfers outside the EEA rely on the European Commission's standard contractual clauses under Article 46(2)(c) GDPR, and on the EU-U.S. Data Privacy Framework where a sub-processor is certified under it. Customers receive advance notice of any sub-processor change and may object within five calendar days.
Things to keep in mind
Risks and trade-offs to weigh before adopting TeltoHeart.
- Never use it in a medical emergency: the terms are explicit that you should call a doctor or emergency services instead
- Do not interpret readings or change treatment on your own; the vendor asks that a qualified professional be consulted first
- The vendor does not guarantee that the information provided is 100% accurate, nor that every function works at all times
- Continuous heart monitoring can feed health anxiety; a flagged irregularity is data for a clinician, not a diagnosis
- Deleting the app stops collection but does not delete data already held on the vendor's servers
- If the wristband came through a clinic, that clinic's privacy policy governs your data and GDPR requests go to it, not to the vendor
- One sub-processor is located in the United States, so some data leaves the EEA under standard contractual clauses or the EU-U.S. Data Privacy Framework
Setup & Integrations
Technical difficulty
Setup is straightforward and needs no medical or technical knowledge. Put on the wristband, install the app on an iPhone running iOS 15 or later or on an Android phone, create a TeltoCare account and, if you want a clinician involved, pick a provider during registration. Pairing happens over Bluetooth and synchronisation is automatic. The only ongoing duties are keeping the battery charged and applying firmware updates, since the service is unavailable without either. Quick start guides, short instructions and a full user manual are published openly. There is no API and nothing to integrate.

Should you pick TeltoHeart?
TeltoHeart occupies a narrow and honest position: a wrist-worn device that produces clinically usable recordings, not a wellness gadget with a heart icon. The CE MDR Class IIa certification, the algorithm co-developed with Kaunas University of Technology and Vilnius University Hospital, and two peer-reviewed papers in Frontiers in Cardiovascular Medicine give the claim a foundation that few consumer wearables can match. The six-lead recording is the concrete difference: three physical electrodes and three derived leads instead of the single lead most smartwatches offer.
The caveat is geographic rather than technical. The value of the product multiplies when a clinician can open your history inside TeltoCare, and the eleven listed practices are all Lithuanian. Elsewhere the workflow degrades to exporting a report or showing a screen during an appointment, which works but loses the continuity that justifies the device. There is no API, so a hospital cannot pull the data into its own systems.
Commercially the offer is refreshingly plain: 100.00 EUR once, three bracelet sizes, a 24-month warranty, no subscription and no upsell to a paid tier. There is also no free trial, and the only way to change your mind is the 30-day free return. The contractual minimum age of 22 is unusual and worth checking before buying for a younger adult.
The privacy posture is solid on paper - named sub-processors, hosting stated as Lithuania, standard contractual clauses, a reachable data protection officer - though the policy dates from August 2023 and says nothing about whether recordings feed the detection algorithm. Anyone buying primarily for the telemedicine loop should confirm first that their own doctor can actually receive the data.
