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).

<h3>Energy drinks and caffeine:</h3>
The current regulation of items containing caffeine is inconsistent, does not serve the interests of consumers, and needs to be changed in a number of different ways. We argue in favor of one of the necessary legislative changes: the Food and Drug Administration (FDA) should mandate that the caffeine quantity be listed on the labels of all consumable items with added caffeine. Foods and beverages that contain caffeine are not currently obliged to list their caffeine amount on the label.
In addition to protecting people who are most susceptible to caffeine-related negative effects, strengthening these weak labeling regulations could increase consumer autonomy and efficient caffeine usage. Customers should be aware of how much caffeine is in the meals and beverages they consume because they have an interest in controlling their caffeine intake.
