Summary:Methods for monitoring cardiovascular conditions, i.e., hyperdynamic circulation, vasodilation, vasoconstriction, or central-to-peripheral arterial pressure decoupling conditions are described. These methods involve measuring a central signal proportional to or a function of the subject's heart activity and a peripheral signal proportional to or a function of a signal related to the central signal. Then calculating a time difference between features in the central and peripheral signals representing the same heart event. The cardiovascular condition is indicated if the time difference is greater or lower than a threshold value, if the time difference is greater or lower than a threshold value over a specified period of time, or if there is a significant statistical change in the times over the specified time period.; These methods can alert a user that a subject is experiencing the cardiovascular condition, which can enable a clinician to appropriately provide treatment to the subject.
