Electrical conduction of heart

Insight and education into the world of the EMT/Paramedic. Lots of useful info for students. And occasionally whatever I feel like posting

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.

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 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."

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…

See in what order the nerve impulses pass through the heart that gives its rhythmicity and the external innervation that controls the rate.

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

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