If the heart stops for more than 8 seconds then the dog will collapse/faint. Sometimes the heart will have another part of the heart initiate a beat to rescue the heart from complete arrest.

As much as we love our smart phones, tablets, and other electronic devices, the EMF they emit can affect the heart rhythm and supercharge the part of our brain that controls the fight-or-flight response. This makes them a potential trigger for PVCs. I know that reducing EMF exposure in this day and age is a big ask, so simply do the best you can.
