摘要: A process for pre-processing recorded and digitised heart sounds corresponding ECG signals is provided. The pre-processed (203) are suitable input into an automatic decision support system implemented by means of a diagnostic network (205), used diagnosing differentiation between normal/functional (206) pathological (207) murmurs, particularly in paediatric patients. includes identifying or predicting locations individual beats within the sound signal, positions S1 S2 pulses respective beats, durations systole diastole segments (302), determining if segmentation signal possible based on selected isolated (305), allowing better feature extraction. invention also provides detecting QRS complex optimizing number beat cycles detected.
