Methods and systems for using seismocardiography-based algorithm for monitoring heart valve operation

Abstract

Methods and systems for monitoring heart valve operation using signals detected by a heart sound sensor includes memory to store program instructions and one or more processors that, when executing the program instructions receive seismocardiography (SCG) signals detected by a heart sound sensor along an axis. The SCG signals include heart sound signals for a series of heartbeats over a first time period. The SCG signals are segmented into SCG segments for corresponding heartbeats within the series of heartbeats over the first time period. A template is calculated based on a first subset of the SCG segments. At least a portion of a second subset of the SCG segments are compared to the template to determine matching scores, and an alert is generated in response to a select number of the second subset of SCG segments having the matching scores that satisfy a matching threshold.
