SYSTEM AND METHOD FOR NON-INVASIVE CARDIOVASCULAR ASSESSMENT FROM SUPRA-SYSTOLIC SIGNALS OBTAINED WITH A WIDEBAND EXTERNAL PULSE TRANSDUCER IN A BLOOD PRESSURE CUFF

摘要

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.
