What s Internal Electrical System Controls The Rate And...

So, what is an arrhythmia? An arrhythmia is a problem with the rate and rhythm of the heart. The heart can either beat too fast, too slow, or with an irregular rhythm. Arrhythmias can also cause the heart to inefficiently pump blood to the body and other organs which can lead to damage in the brain, heart, other organs and can ultimately lead to heart failure. Although most arrhythmias are non life threatening, they can develop into a serious problem. To better understand arrhythmias, it helps to understand the heart s internal electrical system. The heart’s internal electrical system controls the rate and rhythm of each heartbeat. Each heartbeat sends off an electric impulse that tells the heart to contract and pump blood. The electric signal first begins in a group of cells known as the sinoatrial cells or to state simply, the SA node. The SA node is located within the wall of the heart’s upper right chamber, the right atrium. In a healthy adult heart, the SA node fir es off an electrical signal to begin each heartbeat 60-100 times per minute.From here, the electrical impulse travels through special pathways in the atria, making the atria contract and pump blood into the heart’s two lower chambers, the ventricles. The electric signal then passes through a group of cells called the atrioventricular node or the AV node, located between the atrium and the ventricles. Here, the electric signal slows down, allowing the ventricles with enough time to finish filling with blood.Show MoreRelatedThe Heart Of A Heart Disappointment3537 Words   |  15 Pagesresult of underlying coronary illness (Cowie 1997).
