  • Method and apparatus for determining information indicative of cardiac malfunctions and abnormalities
    Patent number: 10492733
    Abstract: An apparatus for determining information indicative of cardiac malfunctions and abnormalities includes a processing device (502) configured to detect amplitude variation from a signal indicative of cardiovascular motion, where the amplitude variation element variation of the amplitude of a wave pattern, e.g. the AO-peak, repeating on the heart-beat rate on the signal. The processing device is configured to determine, at least partly on the basis of the detected amplitude variation, an indicator of cardiac malfunction and abnormality.

  • Method and apparatus for determining information indicative of cardiac malfunctions and abnormalities
    Patent number: 9585580
    Abstract: An apparatus for determining information indicative of cardiac malfunctions and abnormalities includes a processing device (402) configured to extract, from a signal indicative of electromagnetic phenomena related to cardiac activity, a first wave pattern repeating on a heart-beat rate and, from a signal indicative of cardiovascular motion, a second wave pattern repeating on the heart-beat rate. The processing device is configured to form timing data such that each timing value of the timing data is indicative of a time period from a reference point of the first wave pattern belonging to one heart-beat period to a reference point of the second wave pattern belonging to the same heart-beat period. The processing device is configured to determine, at least partly on the basis of the timing data, an indicator of cardiac malfunction and abnormality.
