Abstract
The invention relates to a method and apparatus for real-time assessment of one or more electrical and one or more hemodynamic parameters for the evaluation of cardiovascular fitness. The invention comprises simultaneous analysis of electrical (ECG) and hemodynamic (Impedance Cardiogram—ICG) activities of the heart by evaluating said activities using characteristic points detection method. These points are used for the calculation of electrophysiological parameters such as heart rate (HR) and heart rate variability (HRV) and obtaining the data needed for calculation of hemodynamic parameters such as stroke volume (SV) and cardiac output (CO). The characteristic points detection method significantly improves tolerance to noise and artifacts associated with body movements, thereby enabling the user to assess his/her cardiovascular fitness while being evaluated.
