Abstract
Methods, associated algorithms, and systems for determining cardiac and/or cardiovascular performance from three measurements on a subject are presented, where two of the measurements are provided by plethysmographs and one measurement is provided by an electrocardiogram. The two plethysmographs are placed different distances from the subject's heart. Certain embodiments use the three measurements to calculate intermediate variables of a left ventricular ejection time and a pre-ejection period.
