In one embodiment, a system for identifying a biomedical condition of a subject includes apparatus for collecting blood flow sounds from the subject and a computing device that stores computer-executable instructions that are configured to: receive the collected blood flow sounds, extract acoustic heart pulses from the collected blood flow sounds, segment the acoustic heart pulses to obtain acoustic heart pulse segments, compute a continuous time wavelet transform-based feature for each acoustic heart pulse segment, and perform clustering on the computed continuous time wavelet transform-based features to determine whether or not the subject is experiencing the biomedical condition.

Systems and methods for identifying a biomedical condition

In one embodiment, a system for determining physiological parameters from blood flow dynamics includes a catheter configured for insertion into a blood vessel of a subject through which blood flows, a flexible barrier associated with the catheter configured to oscillate in response to changes in pressure of the blood within the catheter, and a pressure field microphone configured to measure a pressure field induced by the oscillation of the flexible barrier and to generate a measured acoustic pressure signal that can be processed to determine the physiological parameters.
