1. A system for assessing cardiovascular health, comprising: one or more monitoring devices configured to collect pulse rate data from a subject, the pulse rate data including pulse rate measurements and corresponding measurement timestamps, each of the one or more monitoring devices including a first communication interface; and a controller including: one or more second communication interfaces, each second communication interface configured to be communicatively coupled to at least one of the one or more monitoring devices via the corresponding first communication interfaces and to receive the corresponding pulse rate data from the at least one of the one or more monitoring devices; at least one data storage device configured to store the pulse rate data on the at least one data storage device; and at least one processor configured to: (a) select a plurality of recovery periods in the pulse rate data, each recovery period corresponding to a respective decrease in pulse rate from a respective upper pulse rate to a respective lower pulse rate, wherein the respective upper pulse rate is less than a peak pulse rate of the subject or the respective lower pulse rate is greater than a resting pulse rate of the subject; (b) determine an exponential decay from the plurality of selected recovery periods, the exponential decay characterizing a pulse rate recovery for the subject; and (c) provide, via a user interface, the pulse rate recovery for the subject based on the exponential decay.
