Heart Electrical System – Conduction System of the Heart
The heart continuously pumps blood throughout the body. It beats in a rhythmic way. The process of pumping of blood is a involuntary process as it is part of the autonomic nervous system. The heart’s electrical system is responsible for generating and transmitting electrical signals that prompt the heart to contract and pump blood throughout the body. This process ensures that oxygen-rich blood reaches all the organs and tissues, maintaining overall bodily function.
As electricity flows through the heart, it causes each part to contract. This is known as an electrical cascade. While all the cardiac muscles in the heart can conduct electricity, the cascade travels at different speeds in certain areas of the heart — the electrical conduction system. This system includes several key components:
- Sinoatrial (SA) Node
- Atrioventricular (AV) Node
- Bundle of His
- Right and Left Bundle Branches
- Purkinje Fibers
Now, let’s study the conduction system of the heart in detail.
Anatomy and Functions of Heart’s Electrical System
The heart electrical system controls the heartbeat by sending electrical signals through the heart, coordinating the contraction and relaxation of the heart muscles. The conduction system of the heart controls the electrical impulses that coordinate the heartbeat.
Understanding the heart electrical system pathways and the conduction system of the heart flowchart helps us comprehend how the heart beats and maintains a regular rhythm. In this article, we will cover the conduction system of the heart in detail.
