All of the followings are correct about the myogenic pacemaker except, ---------------------

1. They are specialized muscle cells capable of spontaneous activity


2. Latent pacemaker produces an irregular and lower heart rate


3. If the latent pacemaker becomes uncoupled from the pacemaker, it might beat and control a portion of the heart at a different rate.


4. All cardiac cells are electrically coupled, the ones with fastest intrinsic activity will stimulate the whole heart and determine the heart rate


5. After each AP, the membrane undergoes steady depolarization
