An apparatus for determining information indicative of cardiac malfunctions and abnormalities includes a processing device () 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

An apparatus for determining information indicative of cardiac malfunctions and abnormalities includes a processing device () 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.
