A method of diagnosing pathologic heart conditions in which a time series of
heart
sounds is filtered and parsed into a sequence of individual heart cycles. A systolic
interval as well as systolic sub-intervals are identified for each heart cycle.
An energy value is computed for the systolic sub-interval of one or more heart
cycles. The energy value computed is proportional to the energy level associated
with the filtered series of heart sounds. A composite energy value is then computed
for the systolic sub-intervals of one or more heart cycles and compared to a threshold
level in order to distinguish between a normal heart and a pathologic heart. The
system corresponding to the method is comprised of a portable computing device
that manages data collection and stores data collected from new patients, and analyzes data.
