Abstract
An improved method and system for measuring and reporting heart valve activity combines information obtained from independent signals with information obtained from ICG signals, such that signals derived from heart valve activity may be used as confirmation that the ICG system is accurately identifying heart valve activity. The method and system of the present invention also provide improved accuracy in reported values such as PEP, LVET, STR, SV, and CO. In addition, the method and system of the present invention provide improved accuracy of graphical representations of heart activity where the graphical representations include identifying heart valve activity.
