Single-lead ECG Patch
A thin chest patch worn for several days that watches for irregular heart rhythms such as atrial fibrillation and saves only the moments that matter.
Who it is for
Older adults living far from a hospital, for whom a 24-hour Holter test means a long trip and a long wait.
How it works
- Two-electrode ECG
- Remove noise
- Find each beat
- Rhythm model
- Save key episodes
In detail
Two electrodes feed a low-power analog front-end. The patch removes muscle and mains noise, finds each heartbeat, and runs a compact model that looks at rhythm irregularity. Instead of streaming everything, it keeps short episodes around suspicious rhythms and hands them to a phone over Bluetooth at the next check-up.
My part
- Designing the analog front-end and filtering chain for a two-electrode patch.
- Building a rhythm model small enough for a Bluetooth microcontroller.
- Event-based storage to stretch battery life over several days.
Status note In development. Flags rhythms for a doctor to review; it does not diagnose heart disease.
