  • Patent number: 6540687
    Abstract: A method is disclosed for diagnosing, monitoring and treating cardiovascular pathologies. Among the hemodynamic parameters of interest are peripheral resistance, compliance, and cardiac (left ventricular) output. Peripheral resistance determined according to the present invention has been found to be a reliable indicator, not only of hypertension, but also of the cause of the hypertension. The determined peripheral resistance can be compared against a predetermined threshold value. This comparison helps to foster a diagnosis of a hypertensive condition.

  • Patent number: 5879307
    Abstract: A method and device is provided for determining aortic valve abnormalities. The method first includes the step of providing a sphygmomanometer device for inducing a pressure on a body part of a patient. A data stream receiver is provided for receiving a stream of data relating to the pressure response of the pulsed fluid flowing through the cardiovascular system of the patient. A data processor is provided for processing the data to create a series of time dependant pulse wave forms. The data can be converted by Fast Fourier Transformation (FFT) to obtain Power Spectrum (PS) which comprises a frequency dependant array of pulse signals. Both of the time dependant and frequency dependant (Power Spectrum) data can be displayed and analyzed to help determine the condition of the aortic valve and the percentage of regurgitation of the patient.
