Diagram of heart electrical pathway
Did you know?
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. 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 diagram correlates an ECG tracing with the electrical and mechanical events of a heart contraction. Each segment of an ECG tracing corresponds to one event in the cardiac cycle. Visit this site for a more detailed analysis of ECGs. 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…
WebTracing the Heart’s Electrical Pathway. The sinoatrial (sinus) node (1) initiates an electrical impulse that flows through the right and left atria (2), making them contract. When the electrical impulse reaches the atrioventricular node (3), it is delayed slightly. The impulse then travels down the bundle of His (4), which divides into the ...

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.
