Conduction system of the heart | Sinoatrial node, AV Node, Bundle of His, Anatomy and Physiology.

Описание: Let's look at a brief overview of the Cardiac conduction system. In this tutorial you will learn; How the electrical conduction pathway functions in a synchronized manner to contract and relax the atria and ventricles of the heart.

This tutorial shows where the impulses go after being generated in the sino-atrial node. Here's a summary of cardiac events;
1. Sino-atrial node discharges electrical impulse that depolarizes both left and right atria. Both atria contracts
2. impulse reaches atrioventricular node where it is slowed down or delayed.
3. impulse is then transmitted to the bundle of His from him.
4. then to the Left and right bundle branches
5. then to the left and right ventricles and to the Purkinje fibers of each ventricle. Where they contract.
The right ventricle pumps blood to the pulmonary circulation via the pulmonary artery while the left ventricle pumps blood to the systemic circulation via the aorta.
A simple cardiac rhythm on an ECG has a P wave, a QRS complex, and a T wave. Each wave represents an event in the cardiac cycle. Subscribe for easier and to-the-point tutorials. Detailed tutorials coming soon don't miss out. Subscribe here:   / @medicalessentialsplus
