1. A system comprising:
- one or more computer processors;
an electromagnetic-spectrum sensor, the electromagnetic-spectrum sensor configured to capture electromagnetic-spectrum synchronization signals from cardiovascular sensors oriented to a patient; and
one or more computer-readable media having instructions stored thereon that, responsive to execution by the one or more computer processors, enables modules comprising;
a timing module, the timing module configured to precisely assign a reception time to each of the captured electromagnetic-spectrum synchronization signals from the cardiovascular sensors; and
a reception-synchronization module configured to model, based on the precisely assigned reception times for the captured electromagnetic-spectrum synchronization signals, cardiovascular timing of the cardiovascular sensors effective to enable cardiovascular measurements from the cardiovascular sensors to determine a hemodynamic characteristic of the patient.

Abstract
This document describes synchronizing cardiovascular sensors for cardiovascular monitoring, such as through sensing relevant hemodynamics understood by pulse transit times, blood pressures, pulse-wave velocities, and, in more breadth, electrical conduction properties, cardiac rhythms, thoracic impedance, ballistocardiograms and pressure-volume loops. The techniques disclosed in this document use various cardiovascular sensors to sense hemodynamics, such as skin color and skin and other organ displacement. These cardiovascular sensors require little if any risk to the patient and are simple and easy for the patient to use.
