Abstract: A non-invasive apparatus for measuring cardiac mechanical performance of a patient, the apparatus comprising a pressure applying element (301) mountable on a limb of the patient for applying pressure high enough to make a segment of an artery within the limb achieve a collapsed state and empty it from blood at least momentarily; at least one of a plurality of sensors coupled to the pressure applying element, sensing mechanical changes corresponding to volumetric changes in the artery as the artery progressively recuperates from its collapsed state; processing unit (303) communicating with the sensors for receiving output corresponding to the mechanical changes from the sensors and computing factors correlated with blood flow and calculate parameters indicating heart performance.

Abstract: A non-invasive and portable apparatus is provided in order to monitor parameters indicative of heart performance, such as blood flow, and comprises at least one sensor adapted to continuously sense factors correlated with blood flow and collect data related to the flow of blood, the sensor is adapted to be positioned adjacent to a peripheral blood vessel and worn preferably on a wrist. The apparatus further comprises a processor adapted to receive the collected data from the sensor and calculate the parameters indicating heart performance and a monitor on which the parameters indicating heart performance are displayed.
