Ageing is one of the multiple factors associated with electrocardiographic alterations. The normal ageing process induces changes in the cardiovascular system that are reflected in the electrocardiogram (ECG). Heart rate variability (HRV) (i.e., the capacity of the heart to respond and adapt to physiological challenges) which is known to be significantly influenced by age, has also a profound effect on the ECG waveform characteristics. Herein, we investigate age and HRV related changes of the ECG waveform shape using system identification techniques. Previous studies have focused on specific beat-to-beat ECG interval (e.g., QT, PR) variations. Such approaches, however, ignore the wealth of information contained in the remainder of the waveform shape.
