Electrical impulses of the heart

Diagram of heart with order of electrical 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…

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…

The heart is a vital organ that basically serves as a pump. Learn about heart chambers and valves, blood flow, the heart's electrical system and blood supply. Read more about how this amazing organ works.

The heart's electrical system

Cardiac resynchronization therapy (CRT) restores mechanical synchrony in the heart by adding a left ventricular pacing lead to a pacemarker or defibrillator system. Coordinated pacing of the left and right ventriculars allows for resynchronization of ventricular contraction. Approximately 40% of patients with systolic heart failure are candidates for cardiac resynchronization therapy.

PhysioOsteoGram on Instagram: "The Heart’s Conduction System: The Spark Behind Every Beat ⚡ Your heart doesn’t just pump blood—it beats thanks to a specialized electrical system that ensures a steady rhythm. The conduction system starts in the sinoatrial (SA) node, also known as the heart’s natural pacemaker, sending impulses through the atria. These signals then travel to the atrioventricular (AV) node and down through the bundle of His and Purkinje fibers, which make the ventricles…

A person with coronary heart disease has an accumulation of fatty deposits in the coronary arteries. These deposits narrow the arteries and can decrease or block the flow of blood to the heart.

The pumping motion of the heart is a result of electrical impulses that coordinate the contraction of the heart’s chambers.
