Electrical system of the heart

This medical exhibit depicts the electrical system of the heart including the SA node, AV node, Bundle of His, and the Purkinje branches. It includes an EKG as a graphical representation of the ele...

Your cardiac conduction system is the network of nodes, cells and signals that controls your heartbeat. Electrical signals move through your heart, making it beat.

Electrical impulses from your heart muscle (the myocardium) cause your heart to beat (contract). This electrical signal begins in the sinoatrial (SA) node, located at the top of the right atrium. The SA node is sometimes called the heart's "natural pacemaker."

Atrial flutter is a form of heart rhythm disturbance (arrhythmia) caused by electrical system issues in the heart. Atrial flutter is comparable to atrial fibrillation, a common disease in which the heart beats irregularly. The upper chambers of the heart (atria) beat too fast in atrial flutter. #HealthTipsForHealthyLiving

Today I found out how to read an EKG. While some people might say that kind of skill should require 13 years of preparatory school, four years of college, four years of medical school and a specialty in cardiac electrophysiology, I say…Pshaw! It’s not rocket science! If it were, there would be more combustion and potential for speedy projectiles gone [...]

Heart’s electrical system controls all the events that occur when our heart pumps blood. The cardiac conduction system is also called the electrical system. The sinoatrial node (SAN), located…

Back to Basics 🫀 Let's review the conduction system and ECG ⚡️ The cardiac conduction system is also known as the heart's electrical system. We have a network of specialized cells that control the rhythm of the heart by sending electrical signals through the heart. 🫀SA Node: The hearts natural pacemaker, generate electrical impulses that cause the atria to contract 🫀AV Node: Delays the electrical impulse, allowing blood to fill the ventricles 🫀Bundle of His: carries the electrical…

Cardiac conduction system Is the sequence of electrical signals that pass through the heart and ensure cardiac chambers contract in a coordinated manner.
