A Novel Broadband Forcecardiography Sensor for Simultaneous Monitoring of Respiration, Infrasonic Cardiac Vibrations and Heart Sounds. [PDF]

open access: yesFront Physiol, 2021
The precordial mechanical vibrations generated by cardiac contractions have a rich frequency spectrum. While the lowest frequencies can be palpated, the higher infrasonic frequencies are usually captured by the seismocardiogram (SCG) signal and the ...

REDUPLICATION OF HEART SOUNDS. [PDF]

open access: greenJAMA: The Journal of the American Medical Association, 1906
Reduplication means doubling; that is, the sounds still strike the ear, not as a single tone, but as a double tone. Both the first and the second sounds may be reduplicated. The appearance of extra beats is a totally distinct phenomenon. This subject has received scanty attention. Potain, in a study of 500 hearts, makes the first mention in literature.
