Direct Bluetooth connection
Polar H10 connects directly to the smartphone or computer without a separate hardware gateway.
Polar H10 + KardioAS
Polar H10 & KardioAS - ECG recording, RR interval analysis and HRV on Android & Windows.
Polar H10 can be used with KardioAS as a compatible chest sensor for direct acquisition of a single-channel ECG signal and RR interval sequence.
The sensor connects directly by Bluetooth Low Energy to an Android smartphone or Windows computer. No additional controller, hardware gateway or intermediate device is required.
After recording, KardioAS stores the study and provides access to rhythm analysis, heart rate variability, ECG morphology, study comparison, parameter trends and report generation.

01 · Direct connection
From the chest sensor directly to KardioAS.
The current acquisition path is intentionally simple: Polar H10 → Bluetooth Low Energy → KardioAS. The sensor transmits data directly to the supported device, where the recording is stored as a study for later review and analysis.
Saved recording
The session is stored as a study that can be reopened later instead of disappearing after the live screen closes.
Android and Windows
The current Polar H10 workflow is available in the mobile and desktop KardioAS environments.
Local processing
Core recording, analysis and study storage take place in the user-controlled environment.
02 · What is recorded
The source data remain available for analysis.
KardioAS does not reduce the workflow to an average pulse value or a single score. The recorded study remains at the center of the analysis.
Single-channel ECG
The chest-lead electrical signal is stored for visual review and subsequent software analysis.
RR intervals
The sequence of beat-to-beat intervals forms the basis for heart rate variability analysis.
Heart rate
Heart rate is interpreted together with the ECG trace and RR dynamics rather than as an isolated number.
Signal first, analysis second. The original study remains available so the user can return to the source recording instead of relying only on calculated summary values.
03 · HRV analysis
Heart rate variability as a set of complementary characteristics.
The RR interval sequence can be used to examine several aspects of heart rate variability. KardioAS presents multiple analytical views rather than treating HRV as a single universal score.
Time-domain measures
Beat-to-beat variability can be summarized through standard time-domain characteristics.
Spectral analysis
Frequency-domain views provide an additional perspective on the structure of RR variability.
Nonlinear views
Poincaré and other nonlinear representations help visualize patterns that are not captured by a single scalar metric.
- time-domain HRV characteristics;
- spectral characteristics;
- nonlinear measures and Poincaré representations;
- comparison between studies;
- longitudinal tracking of selected parameters.
04 · ECG analysis
From signal review to structural analysis.
The recorded ECG remains available after the session for direct visual inspection and software-assisted analysis.
Original ECG trace
Review the recorded waveform itself instead of relying only on derived metrics.
R peaks and cardiac cycles
Detected R peaks and beat structure provide the timing framework for rhythm and morphology analysis.
Morphology features
QRS-related characteristics and representative beat morphology can be examined when signal quality permits.
Signal quality matters. Morphological interpretation depends on electrode contact, motion artefacts, recording conditions and the characteristics of the individual study. Software-detected P, Q, R, S and T landmarks are available only when the signal quality supports reliable detection.
05 · Longitudinal use
A study remains useful after the recording ends.
Because studies are saved, KardioAS can be used not only for viewing one session but also for repeated review and longitudinal observation.
Compare studies
Review results from different recordings in a consistent study structure.
Follow trends
Track selected parameters over time instead of interpreting every recording in isolation.
Return to the ECG
Reopen the source recording whenever a calculated result needs to be viewed in context.
Generate reports
Create structured reports for individual studies or longer-term trends.
Document repeated sessions
Keep a consistent record of repeated measurements performed under comparable conditions.
Review analysis later
Saved studies can be revisited as new comparisons or analytical questions arise.
06 · Local processing and data control
Core study handling stays in the user-controlled environment.
KardioAS is designed around local recording, local analysis and user-controlled study storage. Core ECG and RR analysis does not require uploading the source recording to an external cloud service.
Fast access to saved studiesPreviously recorded sessions remain available locally for later review.
Less dependence on internet accessCore analytical workflows do not depend on an active cloud connection.
User-controlled storageThe user remains responsible for where studies and exported files are kept.
User-controlled exportReports or files are shared when the user chooses to export or send them elsewhere.
07 · Practical use cases
When this workflow may be useful.
The Polar H10 + KardioAS combination can be relevant to users who need more information than a simple heart-rate display and who want to preserve the original study for later analysis.
RR and HRV research
Explore the structure of beat-to-beat intervals and heart rate variability across repeated recordings.
Single-channel ECG review
Inspect the recorded chest-sensor ECG together with the analytical context of the study.
Repeated measurements
Observe changes between recordings made under comparable conditions.
Training and physiological load
Review how selected physiological parameters change before, during or after repeated physical-load scenarios.
Study documentation
Keep structured records and export reports when documentation is required.
Research and education
Use saved physiological signals for exploratory, educational and non-diagnostic analytical work.
08 · Expandable platform
Polar H10 is the current supported sensor — not the limit of KardioAS.
Polar H10 is the current compatible sensor for the ECG/RR workflow described here. KardioAS is designed as an expandable analytical system rather than a product tied permanently to one sensor model.
The platform is being developed toward support for additional ECG sources, pulse-wave and PPG acquisition, and synchronized multi-signal studies as compatible acquisition modules are implemented and validated.
09 · Important limitations
What should be considered when working with chest-sensor ECG.
Polar H10 provides a single-channel signal from a chest-electrode configuration. This can be useful for rhythm, RR-interval and selected morphology analysis, but it is substantially different from a standard diagnostic 12-lead ECG.
- KardioAS does not replace a diagnostic 12-lead ECG.
- KardioAS does not replace professional medical assessment.
- Software-derived interpretations should not be used as the sole basis for a medical diagnosis.
- The quality of derived results depends on the quality of the source recording.
If symptoms occur or there are concerns about health status, the appropriate action is to seek assessment from a qualified medical professional.
