System for Predicting at Least One Cardiological Dysfunction in an Individual

A system for predicting at least one cardiological dysfunction in an individual comprising:

• means for preparing an ECG recording for an individual having a number n of time-synchronized ECG traces which each comprise a chronological sequence of time signals representing sinus rhythm of a heartbeat of the individual to which at least one P wave, a ventricular QRS complex and a T wave can be assigned in chronological order;
• a selection means for selecting at least two ECG traces from the number n of time-synchronized ECG traces based on a first decision criterion;
• an analysis unit which respectively analyses the selected ECG traces as follows:
• a) determining an isoelectric signal level based on the chronological sequences of time signals from one of the at least two selected ECG traces;
• b) determining a first point in time which is chronologically before the QRS ventricular complex from which time intervals of the selected at least two ECG traces have a signal level deviating from the isoelectric signal level;
• c) determining a second point in time which chronologically follows the first point in time and which is chronologically before the QRS ventricular complex, at which, starting from a signal level, deviates from the isoelectric signal level at which the time signal for the selected ECG trace returns to the isoelectric signal level;
• d) implementing the determining steps a) to c) for all of the selected at least two ECG traces;
• e) determining an earliest first point in time from all of the first points in time determined from the selected at least two ECG traces and a latest second point in time from all second points in time determined from the selected at least two ECG traces;
• and
• f) determining time intervals delimited by an earliest first point in time and latest second point in time corresponding to a known P wave duration;
• and
• a comparator which determines a discrepancy between a known P wave duration and a reference value and which generates a signal based on a second decision criterion.
