How the vest works

A vest that listens to the heart. Machine learning algorithms that hear what the human ear cannot.

The Ticking Heart vest

The vest

A world first. No multi-sensor acoustic vest for detecting coronary artery disease is commercially available anywhere.

  • Six embedded acoustic sensors over the chest
  • Simultaneous recording for one minute
  • Advanced background noise removal
  • Can be used in a typical ward environment
How it works

Why heart sounds reveal a blockage

1

Narrowed arteries make turbulence

Blood forced through a narrowed artery produces faint sounds no ear can hear.

2

Six sensors capture them

Recording from several positions at once separates the signal from noise.

3

Software recognises the pattern

Models trained on angiography-confirmed cases return a screening indication.

If the vest indicates possible coronary artery disease, the person is referred for further tests. The vest does not make a diagnosis.

Safety

Safety and design

Non-invasiveNothing enters the body. Safe, non-invasive.
PassiveThe sensors only listen. USB powered, no battery, no electrical energy to the patient.
RegulatoryWorking towards medical regulatory approval.
