The cardiac conduction system is a group of specialized cardiac muscle cells in the walls of the heart that send signals to the heart muscle causing it to contract the main components of the cardiac conduction system are the sa node, av node, bundle of his, bundle branches, and purkinje fibers. Cardiac conduction system going back to the analogy of the central heating system, the pump, pipes and radiators are of no use unless connected to a power supply the pump needs electricity to work the human heart has a similar need for a power source and also uses electricity. The conduction system consists of specialised heart muscle cells, and is situated within the myocardium there is a skeleton of fibrous tissue that surrounds the conduction system which can be seen on an ecg dysfunction of the conduction system can cause irregular, fast, or slow heart [cardiac] rhythms.
The cardiac conduction system is a highly specialized network of cardiomyocytes within the heart that generate and transmit electrical impulses throughout the heart to coordinate contraction a majority of holt–oram syndrome patients present with conduction system abnormalities ( basson et al, 1994 holt & oram, 1960 newbury-ecob et al, 1996 . Cardiac conduction is the rate at which the heart conducts electrical impulses these impulses cause the heart to contract and then relax the constant cycle of heart muscle contraction followed by relaxation causes blood to be pumped throughout the body. Study exercise 31: conduction system of the heart and electrocardiography flashcards taken from the book human anatomy & physiology laboratory manual.
Specialized myocytes in the heart that conduct the electrical impulses throughout the heart in order of normal conduction, the system consists of the sinoatrial node, the intra-atrial tracts, the atrioventricular node, the bundle of his, the right and left bundle branches, and the purkinje fibers. The electrical conduction in the heart can be monitored by use of an electrocardiogram(ecg) ecg is a non invasive method of evaluating the electrical activity of heart ecg is a non invasive method of evaluating the electrical activity of heart. The cardiac conduction system consists of the following components: - the sinoatrial node, or sa node, located in the right atrium near the entrance of the superior vena cava this is the natural pacemaker of the heart it initiates all heartbeat and determines heart rate.
A 12-lead view of the heart is the industry standard for assessing the electrical conduction system of the heart, enabling physicians to identify the exact location of weakened heart muscles, as well as providing more comprehensive data on arrhythmias and ischemia.
