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. 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. ricky mineo baseball

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. ricky miller obituaryElectrical 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… ricky minds the baby
