摘要：
Systems and methods are provided for using information from a subject heart sound signal and information from a subject physiological pulsatile signal to identify subject systolic time intervals. An example system for identifying systolic time intervals includes a heart sound detector circuit, configured to detect a subject heart sound signal using an acoustic signal. The system can include a physiological signal sensing circuit configured to detect a physiological pulsatile signal, including at least one of a pulsatile cervical impedance signal or a pulsatile pulmonary artery pressure signal. A timing circuit can be configured to calculate a systolic time interval between a feature on the heart sound signal and a feature on the pulsatile signal. A subject physiologic diagnostic indication can be provided using information from the timing circuit about the systolic time interval.
