Yes
Your heart would not beat in a regular pattern. The pacemaker (the natural one) is there to control the beat of your heart which is why when you run your heart beat gets faster to pump more blood around the body. If you do not have one then your heart beat wont beat fast enough if your running or maybe not fast enough at all. That is even if it beats at all>
stimulation from the Sino Atrial node: SA node
No, damage to the AV node causes total heart block, in which signals from the atria fail to reach the ventricles and the ventricles beat at their own intrinsic rhythm of 20 to 40 bpm.
If by "stomach" you mean "abdomen", then yes. The rhythmic beating felt in the lower abdomen is the abdominal aorta pulsating with each beat of the heart. In healthy individuals, it is completely normal. If you are at all concerned about your own heart beat being felt in your abdomen, have your doctor take a look.
Also known as the intrinsic conduction system of the heart, it helps the heart beat even when a part of the heart is damaged. However,if one of the 5 parts of the nodal system are damaged, it can cause abnormal heart beat irregularities.1. sinuatrial node2. atrioventricular node3. bundles of his4. bundle branches5. purkinje fibersIrregularities include tachycardia, bradycardia, heart block, fibrillation, arrhythimas.
