Separation of electrocardiographic from electromyographic signals using dynamic filtration

Electromyographic (EMG) signals of surface placed muscles are often used for: estimation of the force developed by a muscle [1]; conclusions about the role of different types of muscle motor units in different motor tasks [2,3]; analysis of changes in muscle functioning caused by different neuro-muscular diseases [4,5]; control of different technical devices as ortheses [6,7], exoskeletons, prosthesis, etc. It is clearly visible that electrocardiographic (ECG) signals superimpose the EMG signal when some of the investigated muscles are trunk muscles and especially for those ones placed on the left.
