ECG acquisition, real-time transmission, clinical intelligence, and patient interface — engineered from day one as a single integrated system.
01 · Acquisition Layer
Signal acquisition starts here. Medical-grade single-lead ECG at 500 Hz / 24-bit, streaming over Bluetooth LE with built-in accelerometer and temperature sensing.





500 Hz sampling helps preserve key ECG waveform details, while 24-bit signal resolution supports precise measurement of subtle electrical activity. Together, they provide high-fidelity ECG data for rhythm monitoring, HRV analysis, and clinical research applications.
One full charge supports over 24 hours of continuous recording. Two-device rotation enables uninterrupted multi-day monitoring without single-use patch costs.
Streams ECG data to the VitalSigns Hub or VS-Check app with low latency and extended range. No wired connection required between sensor and relay.
3-axis motion data helps distinguish artifact from arrhythmia. Skin temperature adds a physiological layer for post-operative and RPM workflows.
Cleared under FDA 510(k) K243003 as a Class II prescription device. Manufactured under an ISO 13485 quality management system.
02 · Transmission Layer
Signal captured — now delivered. Forwards ECG to the cloud over Wi-Fi or LTE with automatic failover. Pairs with third-party vital sign devices — one gateway for every sensor.




Wi-Fi and cellular LTE downstream. The right radio for every deployment — hospital, home, or field.
Simultaneously pairs with ECG, blood pressure, SpO2, and temperature devices over one Bluetooth radio. Replaces multi-vendor monitoring carts.
If one Wi-Fi network drops, the hub reconnects to a backup Wi-Fi without losing data. Continuous monitoring stays continuous, even when the network isn't.
Continuous waveform forwarded to VS-KARDIA cloud — not batched uploads. Clinicians see what the heart is doing right now.
03 · Clinical Intelligence
Where every signal converges. Multi-patient dashboard with rhythm classification, configurable alerts, and EHR integration — continuous and on-demand data in one time-aligned view.



One workspace for every patient on the platform. Continuous streams, on-demand recordings, and multi-vital data converge into a single time-aligned record per patient.
Built-in rhythm classification flags arrhythmias and computes interval measurements automatically — so clinicians spend their time reviewing the events that matter, not scrubbing through hours of strip.
REST API and HL7/FHIR endpoints push reports and waveform artifacts into the EHR your team already uses. No re-keying, no parallel record.
04 · Patient Interface
For on-demand workflows, the patient connects directly. Tap to capture ECG via Bluetooth LE, see the waveform live, and sync recordings to VS-KARDIA automatically.




The app pairs directly with the VSH101 sensor over Bluetooth Low Energy. No hub required — the phone is the relay.
One tap starts a recording the moment a symptom occurs. Capture exactly the window that matters — the diagnostic value of an ECG is highest at the moment of symptom.
Patients see their ECG in real time during recording. Heart rate, rhythm, and waveform are visible at-a-glance — reassurance built into the workflow.
When cardiac symptoms occur, patients can record a short ECG session anytime, anywhere, helping capture the rhythm at the moment it matters most.
