"WebAn electrocardiogram (ECG) represents the electrical current moving through the heart during a heartbeat. The current's movement is divided into parts, and each part is given an alphabetic designation in the ECG. Each heartbeat begins with an impulse from the heart's pacemaker (sinus or sinoatrial node).

WebThe electrical signals that travel through your heart conduction system cause your heart to expand and contract. These contractions control how blood flows through your heart. Ideally, the electrical conduction system keeps up a steady, even heart rate. WebThis article will discuss the components of the heart’s conduction system including their anatomy and clinical significance. The heart has two main types of cells: 1. Conducting cells: generate and propagate electrical …

WebA normal heartbeat begins with an electrical impulse from the sinus node, a small area in the heart's right atrium (upper chamber). PSVT occurs because of a short circuit — an abnormal electrical pathway made of heart cells — that allows electricity to speed around in a circle and repeat the signal over and over. Electrical signals arising in the SA node (located in the right atrium) stimulate the atria to contract. Then the signals travel to the atrioventricular node (AV node), which is located in the interatrial septum. After a short delay that gives the ventricles time to fill with blood, the electrical signal diverges and is conducted through the left and right bundle branches of His to the respective Purkinje fibers for each side of the heart, as well as to the endocardium at the apex of the heart, t…
