Signal Quality
That Reveals More
Medical-grade ECG acquisition, real-time streaming, and verified engineering — from signal to clinical insight.
01The Signal Layer
ECG Captured at the Diagnostic Standard — 500 Hz, 24-bit
How much an ECG can tell you comes down to two things: how often the signal is sampled, and how wide a range each sample can faithfully measure. Most wearable patches sample at 125–256 Hz through a 12- to 16-bit front end — enough to confirm a rhythm, not enough to preserve the waveform detail that clinical decisions depend on. VitalSigns captures at 500 Hz through a 24-bit front end — the diagnostic-grade tier.
What 500 Hz / 24-bit actually preserves
- 1Precise R-peak timing500 Hz preserves the sharp morphology of each QRS complex. That precision is what accurate RR-interval and HRV measurement depend on — the foundation for autonomic and cardiac-risk assessment.
- 2P-wave shape preservedThe low-amplitude P-wave is the first waveform that lower sampling rates blur. Keeping its shape intact matters for any rhythm assessment where atrial activity is clinically relevant — including AF screening, one of the most common reasons a physician orders extended ECG monitoring.
- 3Baseline stability through extended wearA 24-bit front end provides the dynamic range to ride through electrode offset, skin impedance drift, and baseline wander — without clipping or saturating. The signal stays clean across hours of continuous recording, not just the first few minutes.

02The Transmission Layer
Real-Time Streaming, Not Delayed Review
Traditional ambulatory ECG workflows store data on the device and review it after upload or after the monitoring period ends — creating a gap between when a cardiac event occurs and when clinicians can review the waveform.
VitalSigns is designed for continuous ECG waveform streaming when paired with the Hub. Data flows from sensor to cloud in real time — supporting live visualization, cloud-based analysis, and alert-driven clinical workflows.
Moving a continuous ECG is the hard part
Capturing 500 Hz, 24-bit ECG is one problem. Streaming it continuously off a 16.5 g, rechargeable patch is another. Bluetooth Low Energy's real-world throughput is a fraction of its headline rate, and a continuous raw ECG waveform eats much of what's left — which is why most medical patches store on the device and upload later, or fall back to a cable.
VitalSigns takes a different path. Proprietary on-device compression shrinks the waveform before it reaches the radio, and a purpose-built streaming protocol keeps the link continuous and recovers cleanly from dropouts. Fewer bytes over the air means the radio is on less — low enough power to stream around the clock — and the compression is tuned to preserve clinically relevant morphology, not just shrink a file.
- Continuous, not store-and-forwardMost patches buffer on the device and upload later. VitalSigns streams live.
- Compressed without losing the signalTuned to keep diagnostic morphology intact — measured by PRD (percent root-mean-square difference), an objective signal-fidelity metric, not by adjective.
- Low power by designLess time on the radio is what makes 24/7 streaming feasible on a light, rechargeable patch.
- Designed for gap-free recordingBuffering and auto-reconnect bridge BLE dropouts, keeping the trace continuous through real-world interference.
Why real-time transmission matters
