What is the atrioventricular node?
A complex system controlled neurons and electrical impulses control the heart function. This system includes atrioventricular node. This collection of nerve and muscle cells is located between the atria and the chambers in the area called Koch's Triangle and performs signals between the upper and lower chambers of the heart. Atrioventricular node is sometimes referred to as AV node A, rarely as an aschoff-drawa node. The discovery of the atrioventricular node itself is credited to Sunao Tawar, but his work coordinated with the work of various other students of the same anatomical area in the same time frame. The work, which occurred at the beginning of the 20th century, also built on research from the second half of the 19th century. The sinoatrial node is located in the right atrium and acts as a pacemaker. When the node SA creates a signal, this signal must go through the atrioventricular node. To ensure optimal heart function and correct blood flow, anthrioventricular node slows this signal so that chambers or lower chambers of the heartThey did not let go until the atrium, the upper house, was fully incomplete. Reducing the speed of signal movement is usually only one tenth of a second.
node Sa signals the heart to accelerate or slow down, and adjusts its signals to the needs of the body. During exertion, stress or other situations that require oxygen to be supplied faster to the body cells, the node accelerates its signals. The atrioventricular node then relieves these signals so that different chambers of hearing work in a coordinated way.
When the atrioventricular node function is impaired, this can lead to problems in the heart like arrhythmia. Arrhythmia is any irregularity in the rhythm of the heart and is sometimes caused by failures in electrical systems that control the heart rhythm. Among the different types of arrhythmias are bradycardia when the heart beats too slowly; Tachycardia when it beats too fast; rhythms that occur too earlyas premature contraction; and fibrillation about irregular, uncoordinated heart rhythm. Some arrhythmias may be harmless, but sometimes they must be treated with medicines or by placing an artificial cardiac.
