Four Layers.One Signal Path
ECG acquisition, real-time transmission, cloud data platform, and patient interface — engineered from day one as a single integrated system.
01 · Acquisition Layer
ECG SensorVSH101
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.
Signal resolution that preserves clinical detail
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.
Rechargeable with 24-hour battery life
One full charge supports 24 hours of continuous recording. Two-device rotation enables uninterrupted multi-day monitoring without single-use patch costs.
Real-time wireless transmission
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.
Accelerometer + skin-temperature sensors
3-axis motion data helps separate movement artifact from true signal. Skin temperature adds a physiological layer for post-operative and RPM workflows.
FDA-cleared, ISO 13485 certified
Cleared under FDA 510(k) K243003 as a Class II prescription device. Manufactured under an ISO 13485 quality management system.
02 · Transmission Layer
Gateway HubVSG101
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.
Multi-Band Connectivity
Wi-Fi and cellular LTE downstream. The right radio for every deployment — hospital, home, or field.
Multi-device pairing
Simultaneously pairs with ECG, blood pressure, SpO2, and temperature devices over one Bluetooth radio. Replaces multi-vendor monitoring carts.
Automatic failover
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.
Real-time cloud streaming
Continuous waveform forwarded to VS-KARDIA cloud — not batched uploads. Clinicians see what the heart is doing right now.
03 · Clinical Platform
Cloud PlatformVS-KARDIA
Where every signal converges. Multi-patient dashboard with waveform review, trends, and reports — continuous and on-demand data in one time-aligned view.
Multi-patient dashboard
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.
Full ECG waveform review
Continuous recordings arrive time-aligned and fully indexed, so clinicians can move straight to the segment they need instead of scrubbing through hours of strip.
EHR integration
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
Mobile AppVS-Check
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.
BLE pairing with VSH101
The app pairs directly with the VSH101 sensor over Bluetooth Low Energy. No hub required — the phone is the relay.
On-demand recording
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.
Live waveform display
Patients see their ECG in real time during recording. Heart rate, rhythm, and waveform are visible at-a-glance — reassurance built into the workflow.
Automatic cloud sync
When cardiac symptoms occur, patients can record a short ECG session anytime, anywhere, helping capture the rhythm at the moment it matters most.
