WHO WE ARE
Heliora Health B.V.
The Hague, Netherlands
Heliora Health is developing an ECG-based physiological monitoring system designed for long-term data collection in everyday life.
The product concept brings together ECG textile, a compact recorder, a mobile app and analytical software. It is designed to organise repeated recordings and selected context into a structured personal timeline.
Heliora is currently focused on product development, technical evaluation, user-experience research and the conformity assessment process.
Electrical heart profile and dry-textile channel consensus.
ECG textile · compact recorder · mobile app · analytics
Multiple views of cardiac electrical activity captured through dry textile electrodes.
ONE CONNECTED SYSTEM
From wearable recording to a structured personal timeline.
Heliora is being developed as a connected system in which the textile, recorder, mobile app and analytical platform work together.
ECG textileIntegrated dry electrodes are designed to collect multi-lead ECG signals without gel or adhesive patches.Compact recorderThe recorder captures the signal and transfers recording data to the connected digital environment.Mobile accessThe mobile interface is being developed to show recording status and allow selected moments and context to be added.Structured data presentationRecordings and participant-provided context can be organised into a longitudinal overview.
WHY THE HEART
The heart does not behave the same way every hour of every day.
Cardiac activity can change during sleep, physical activity, recovery, travel, stress or other everyday situations. A short recording represents a limited period. Repeated recordings can provide a broader view of how recorded signals vary over time. Heliora is being developed to explore how longer observation periods and selected context can be organised and presented clearly.
WHY OBSERVATION TIME MATTERS
Relevant events may occur outside a short recording window.
19.8 million
Cardiovascular deaths worldwide each year.
Published research has shown that, within the studied patient group, longer monitoring periods identified arrhythmias in more participants.
FIRST 48 HOURS · CASE STUDY43.9%
UP TO 14 DAYS · CASE STUDY62.2%
THE GAP BETWEEN ISOLATED RECORDINGS
One gap. Different perspectives.
“Something happened, but it was not captured.”
Occasional sensations or marked events may not coincide with a scheduled ECG or another short recording period.
A single recording may not contain the full timeline.
A specialist may see the information collected during a particular examination without seeing what happened at other times.
The event ends. The timeline continues.
Changes may occur over days, weeks or months. Longer observation can create continuity between individual recording periods.
Heliora is not currently intended to provide a medical report, diagnosis or clinical interpretation.
Information must not be used for clinical decision-making.

PERSONAL PHYSIOLOGICAL MODEL
Recorded data becomes more meaningful when context is part of the picture.
Heliora is developing a personal physiological model that can connect recording history with context selected by the user.
ECG + SELECTED CONTEXTRecording history + context
Repeated ECG recordings can create a structured history of an individual recording pattern.
Sleep, activity, travel, symptoms, therapy or other information is added only when the user chooses.
The product is being developed to organise recordings and context into a clearer personal overview - not a diagnosis, clinical interpretation or automated medical verdict.
Graph model developed with Xplore Intelligence, UK.
YOUR RECORDINGS, ORGANISED

Heliora is being developed to bring recording sessions, marked moments and selected context into one structured timeline.
- Review recordings from different observation periods
- See marked moments and selected context together
- Follow how recorded data changes over time
- Choose what information to export or share
- Present information in a clearer, more structured format

HELIORA FOR INDIVIDUALS
A personal view of how your heart changes over time.
Heliora is developing a future experience that could help individuals explore how multi-lead ECG recordings change across everyday life and over longer periods.
By bringing recordings together with context selected by the individual, Heliora could create a clearer picture of patterns around sleep, activity, recovery, travel, stress, symptoms and therapy.
