Generalised Subtraction Procedure for Removing Power-Line Interference from ECG: Case of Powerline Frequency Deviation
The present work continues the generalisation of the subtraction procedure, which removes the power-line interference without affecting the components intrinsic to the ECG. It is based on previous investigations, dealing separately with the cases of odd and even multiplicity/non-multiplicity between the sampling rate and the power-line frequency. The study proposes a common equations and algori...
متن کاملRemoving ECG Artifact from the Surface EMG Signal Using Adaptive Subtraction Technique
Background: The electrocardiogram artifact is a major contamination in the electromyogram signals when electromyogram signal is recorded from upper trunk muscles and because of that the contaminated electromyogram is not useful.Objective: Removing electrocardiogram contamination from electromyogram signals.Methods: In this paper, the clean electromyogram signal, electrocardiogram artifact and e...
متن کاملPowerline Interference Suppression in High-Resolution ECG
The efficacy of four powerline interference suppression methods was tested for application in highresolution electrocardiogram (ECG). The goal was minimal distortion of the original signal micro-potential waveform, combined with maximum noise reduction. Simulated low amplitude His-bundle potentials were used for the evaluation. Several objective parameters were measured, such as mean square err...

متن کاملPowerline Interference Reduction in ECG Using Combination of MA Method and IIR Notch
The ECG Signal is a graphical representation of the electromechanical activity of the cardiac system. It is one of the most important physiological parameter, which is being extensively used for knowing the state of cardiac patients. For diagnostic quality ECG recordings, signal acquisition must be noise free. Since ECG signals are only of the order of 1 mV in amplitude, the ECG acquisition is ...
