A method and apparatus are disclosed for non-invasively determining a cardiovascular status of a patient. Cardiac pulse waveforms associated with the peripheral artery are monitored during a plurality of cardiac ejection cycles, using a wideband external pulse transducer. The waveforms are analyzed to obtain information relating to the patient's Augmentation index (AI), cardiac performance, and/or cardiac stroke volume.
L'invention concerne un procédé et un appareil de détermination non-invasive de l'état cardiovasculaire d'un patient. Les ondes cardiaques associées à l'artère périphérique sont surveillées pendant plusieurs cycles d'éjection cardiaque, au moyen d'un transducteurs d'impulsions externes. Les formes d'ondes sont analysées de manière que les informations relatives à l'indice d'augmentation, à la puissance cardiaque et/ou au volume d'éjection systolique du patient soient obtenues.
