WebNov 18, 2024 · For the heart to beat properly, the signal must travel down a specific path to reach the ventricles (the heart's lower chambers). When the heart's natural pacemaker is defective, the heartbeat may be too fast, too slow or irregular. Rhythm problems also can occur because of a blockage or abnormality of your heart's electrical pathways. 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).

WebYour heart has four chambers. The chambers are like rooms in the “house” of your heart. If you look at a diagram of a heart, these chambers divide into upper and lower chambers … 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.
