Abstract
Devices, systems, and methods are described for acquiring heart sound timing content to enhance pulse waveform analysis.
Claims21
A band-based apparatus for heart sound and pulse waveform acquisition, the apparatus comprising:
- an elongate band adapted to encircle a human body part;
- a first sensor positioned along the band and adapted to measure heart sound;
- and
- a second sensor different from the first sensor, wherein the second sensor is adapted to measure a pulse waveform.
1 more element
A patch-based apparatus for heart sound and pulse waveform acquisition, the apparatus comprising:
- a body;
- an adhesive region adapted to attach the body to a subject's skin;
- and
- at least one sensor adapted to acquire heart sound and a pulse waveform.
1 more element
A method for heart sound and pulse waveform acquisition and analysis, the method comprising:
- acquiring a pulse waveform at a first location;
- acquiring heart sound at a second location;
- and
- determining a Dicrotic Notch timing position for the pulse waveform by superposition of the pulse waveform and the heart sound.
