Fig. 8. Clinical evaluation of PWS electrodes for ECG and EMG.

Fig. 8

a ECG signals showing the variability in the R-R intervals and absent P-waves, which are diagnostic of atrial fibrillation. b EMG signals showing a brief and significant increase in muscle potentials detected using the PSW dry electrode by tapping on the biceps tendon. c EMG signals showing incremental potentials during contraction of the biceps muscles, which decreased following relaxation.
