This part of labor is called the latent phase. Latent phase labor can last hours or days, but is usually measured in a few hours. Latent phase labor is considered abnormal (prolonged latent phase), if it lasts longer than: 20 hours in a woman having her first baby, or.

I know that the contraction of ventricles starts after sufficient influx of Ca2+ and threshold potential is met. The influx of Ca2+ is at start of Phase 2, so Phase 0 and 1 are included in the latent period. Comparing to electrocardiogram is not simple, since there is always at least some time lag between the event and the recording. I think there not much sense to compare cellular model events to ECG recordings here.
