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… " - Diagram of heart electrical pathway

WebJun 24, 2024 · An artificial pacemaker is a small electrical device commonly fitted to monitor and correct heart rate and rhythm. It is inserted into the chest under the left clavicle, with wires connected to the heart via the venous system. The most common indication for a pacemaker is bradycardia. WebThe heart’s electrical system controls all the events that occur when your heart pumps blood. Each beat of your heart begins with an electrical signal from the sinoatrial node, called SA node. The signal is generated as the two vena cavae fill your heart’s right atrium with blood from other parts of your body.
