摘要
Method and apparatus for diagnosing heart failure are disclosed. They include monitoring a subject's pulsatile blood flow with a non-invasive probe during a Valsalva maneuver (VM), processing data therefrom to calculate fall in flow, hear rate changes, Rebound, and heart stroke volume during the VM. Monitored and calculated results are compared to defined thresholds and interpreted and reported. The apparatus takes the form of a pulsatile blood flow probe on a finger or toe or in a mouthpiece facilitating the VM, the mouthpiece optionally including a pressure transducer or digital monometer to ensure that the subject is performing the VM within required pressure and time ranges. The method and apparatus include a controller or digital processor for processing and reporting the results of the monitoring, calculations, comparisons, interpretation, and reporting of the diagnostic results.
