Implication

May aid objective EMG analysis in preclinical models; leaves open clinical translation pending human validation.

Structured PICO

P
Population
Human diaphragm electromyogram (EMGdi) (n=5) obtained with esophageal electrodes, mongrel dog EMGdi (n=5) obtained with intramuscular electrodes, and computer-simulated power spectra.
I
Intervention
Computer algorithms for automatic selection of EMGdi free of electrocardiogram and numerical quantification of common artifacts.
C
Comparator
Other methods, including careful visual selection of time domain signals by experienced analysts.
O
Outcome
Reliability and reproducibility of quantifying signal disturbances (noise, electrode motion, esophageal peristalsis, non-QRS ECG activity).surrogate

Frequency domain application of computer algorithms offers a reliable and reproducible means to objectively quantify sources that contaminate the interference pattern EMG.
