摘要：
Certain aspects of the instant disclosure are sensing and/or providing estimates for blood pressure or cardiac output by using time-synchronous communication (or correlation) between two sensors. Specific embodiments concern an arrangement of devices including a time-synchronous circuit and a sensor. The sensor is configured to obtain, at or near a lower-body/extremity location of the user, time-related data indicative of speed or transit time of a propagating pressure wave while the wave travels in an artery and down a leg of the user. The time-synchronous circuit is configured to correlate information corresponding to or derived from the time-related data in a time synchronous manner with other cardiovascular information. The cardiovascular information corresponds to or is derived from hemodynamic output from the user by another sensor located at or near an upper-extremity location or lower-extremity of the user.
