Explanation:
Pacemaker cells, unlike other neurons in the body, can depolarized themselves (and therefore can fire action potentials) without the need of an external innervation of the autonomic nervous system.
Each class of pacemaker cells has its own intrinsic rate.
For example, sinoatrial node rate is 60-100 bpm (the normal heart frequency).
The atrioventricular node is also part of the electrical conduction system of the heart. When the sinoatrial node fails, atrioventricular node takes the lead (40-60 bpm).

Metabolic alkaloiss is developed by body when it loses too much acid or gains too much base then excess vomiting which causes electrolyte loss, adrenal disease ,loss of potassium or sodium in a short amount of time.
Concomitant NH4+ losses in the diarrhea fluid may also contribute to development of metabolic alkalosis when hyperchloremic acidosis caused by the loss of too much sodium bicarbonate from the body which can happen with severe diarrhea.
