An apparatus for producing information indicative of cardiac malfunctions, for example atrial fibrillation, includes a processing system for processing an analysis signal produced by a sensor system responsive to motion including cardiovascular motion. The processing system is configured to form a first indicator quantity indicating degree of concentration of the autocorrelation of the analysis signal to a point corresponding to zero time difference between analysis signal samples whose mutual correlation is expressed by the autocorrelation and a second indicator quantity indicating the spectral entropy of the analysis signal. The processing system is configured to determine an indicator of cardiac malfunction on the basis of at least the first indicator quantity and the second indicator quantity.

Method and apparatus for producing information indicative of cardiac malfunctions

An auxiliary unit, adapted to be coupled to a mobile station comprising a basic element containing components necessary for data transmission, analyses and storage, as well as a sensor element containing a sensor suitable for the non-invasive measuring of a person's bodily functions and the special electronics required by the sensor. This means that different kinds of non-invasive measurements, such as ECG, EEG, EMG, blood pressure and respiratory flow, can be taken by changing the mere sensor element.
