Systems and methods for monitoring and analyzing cardiovascular states

A system for determining a cardiovascular state of a patient in a stress condition, the system comprising:

• at least one sensor configured to received one or more signals from the patient;
• a computing device in data communication with the at least one sensor;
• a non-transitory, computer-readable storage medium in operable communication with the computing device;
• an input device in operable communication with the computing device;
• and
• an output device in operable communication with the computing device;
• wherein the computer-readable storage medium contains one or more programming instructions that, when executed, cause the computing device to:
• receive at least one signal in the time domain from the at least one sensor, wherein the at least one signal in the time domain is a pulse wave measurement of the patient;
• determine at least one metric in the time domain from the at least one signal in the time domain;
• determine at least one metric in the frequency domain from the at least one signal in the time domain;
• derive one or more sets of parameters using the at least one metric in the time domain and the at least one metric in the frequency domain, a set of parameters being associated with a particular cardiovascular state;
• evaluate temporal variations of the parameters within the one or more sets of parameters;
• and
• determine the cardiovascular state of the patient from a combination of the temporal variations of parameters in a set of parameters and information from at least one database of cardiovascular states that are associated with the sets of parameters.
