Real-time EHG analysis by application of the nonlinear correlation coefficient H2 to two adjacent bipolar signals. The analysis on the left concerns an EHG segment with no contractions (bottom line) associated with a poor correlation between the signals (H2 = 0.18). The analysis on the right concerns an EHG segment during a contraction associated with a strong correlation between the signals (H2 = 0.9)
