Heart conduction

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…

Electrical impulses travel from the SA node to the AV node, through the bundle of His, and finally to the Purkinje fibers.

Diagram of heart with order of electrical conduction

The cardiac conduction system refers to how the heart contracts. Here we explain how electrical impulses ensure it beats regularly.

The heart is a muscle that pumps blood through the body. Learn about each part of the heart including what each part looks like, its specific function and its location.

An overview of the cardiac conduction system including the sinoatrial node, atrioventricular node, the bundle of His and Purkinje fibres.

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.

The cardiac conduction system is a group of specialized cardiac muscle cells in the walls of the heart that send signals to the heart muscle causing it to contract. The main components of the cardiac conduction system are the SA node, AV node, bundle of His, bundle branches, and Purkinje fibers.

How the Heart Works: Diagram of Heart Blood Flow Cardiovascular System Anatomy and Physiology Pathway of Blood in the Heart Circulation of blood through the heart Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. As the … Continue reading Diagram of Heart Blood Flow for Cardiac Nursing Students

What makes the heart beat? Learn about the conduction system, an incredible machine.

Kristine Tuttle on Instagram: "Electrical Conduction of the Heart⚡️🫀 ⚡️SA node (Sinoatrial node): Primary pacemaker of the heart; creates electrical impulses of 60–100 bpm ⚡️AV node (Atrioventricular node): Secondary pacemaker of the heart, or “backup pacemaker.” Takes over at a rate of 40–60 bpm if the SA node malfunctions. ⚡️Bundle of His: Transmits electrical impulse from AV node → bundle branches ⚡️Bundle Branches: Delivers impulses to Purkinje fibers ⚡️Purkinje fibers: Fire at a…

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…

This cardiac pacing device is placed in the chest to help control the heartbeat. Know when you might need one.

Interventricular Septum - (IVS), (or ventricular septum, or during development septum inferius), is the stout wall separating the lower chambers (the ventricles) of the heart from one another.
