Signals
Four signal domains recorded together from the chest: seismic cardiography (SCG), acceleration, acoustics, and ECG.
Four signal domains
Seismic cardiography
SCG records the small vibrations of the chest wall that accompany the heartbeat.
Acceleration
Motion of the chest and torso, used to place cardiac events in a mechanical context.
Acoustics
Heart and lung sounds captured at the surface of the chest.
ECG
The electrical activity of the heart, recorded alongside the mechanical and acoustic channels.
