Abstract
The exemplified methods and systems facilitate one or more dynamical analyses that can characterize and identify synchronicity between the acquired cardiac signals and photoplethysmographic signals to predict/estimate the presence, non-presence, localization, and/or severity of abnormal cardiovascular conditions or disease, including, for example, but not limited to, coronary artery disease, heart failure (including but not limited to indicators of disease or conduction such as abnormal left ventricular end-diastolic pressure disease), and pulmonary hypertension, among others. In some embodiments, statistical properties of the synchronicity between the cardiac signals and photoplethysmographic signals are evaluated. In some embodiments, statistical properties of a histogram of the synchronicity between the cardiac signals and photoplethysmographic signals are evaluated. In some embodiments, statistical and/or geometric properties of a Poincaré map of synchronicity between the cardiac signals and photoplethysmographic signals are evaluated.
