Abstract
The present invention relates to a method and a system for carrying out the method of determining at least one cardiovascular quantity of a mammal. The method comprises (i) selecting a measuring site of a vessel; (ii) determining or estimating a mean diameter of the vessel at the measuring site; (iii) determining a pulse wave velocity and/or another elasticity related quantity of the vessel at the measuring site; (iv) determining a distension of the vessel at the measuring site; and (v) calculating the at least one cardiovascular quantity from the determined mean diameter, elasticity related quantity and distension of the vessel at the measuring site. The cardiovascular quantity system comprises (i) a plurality of sets of electrodes where each set of electrodes comprising at least two electrodes can be attached to a skin surface of the mammal such that capacitive coupling through the skin surface and between the electrodes of the set of electrodes is provided when an electrical signal is applied over the electrodes at a measuring site of a vessel; (ii) electrical devices for applying an electric oscillating signal over the respective sets of electrodes; (iii) at least one processor…
