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>What is blood transfusion?</h3>
Intravenously putting blood components into a person's circulation is known as a blood transfusion. For a number of medical disorders, transfusions are performed to replenish lost blood components.
Patients who have sustained major injuries in vehicle accidents or natural disasters are treated with blood transfusions. Blood transfusions are frequently given to people who have a condition like leukemia or kidney disease, both of which can induce anemia.
Through a little tube inserted into a vein in your arm, donated blood is given to you as part of a standard medical operation known as a blood transfusion. Blood lost during surgery or an accident can be replaced with the aid of this potentially life-saving technique.

12 years of school, four years of college and four years of medical school.
The first year of training after medical school is called an internship, or more commonly it is called first year of residency or PGY-1 (Post-Graduate Year-1). The following years are called PGY-2, PGY-3, etc. The training that is done after a residency (in a subspecialty) is usually called a fellowship. Much of what you will learn in your chosen specialty will be learned in your residency.
