Implication

May enhance ECG signal quality amid frequency shifts; leaves open prospective clinical validation.

Structured PICO

P
Population
Electrocardiographic signals subject to powerline interference
I
Intervention
Parameter-varying notch filter with tuning mechanism implemented on a chpKIT max32 as a discrete-time system
O
Outcome
Tracking deviations of the frequency associated to the power line interference, keeping a narrow stop band with a reduced transient response

A novel parameter-varying notch filter effectively removes power line interference from ECG signals while tracking frequency deviations and minimizing transient response.

Cite This Study

Dector et al. (2015) studied Electrocardiographic signals subject to powerline interference. Parameter-varying notch filter with tuning mechanism vs. Adaptive filters with a high quality factor was evaluated on Tracking deviations of the frequency associated to the power line interference, keeping a narrow stop band with a reduced transient response. A parameter-varying notch filter with a tuning mechanism successfully tracked frequency deviations of power line interference in ECG signals while maintaining a narrow stop band.
