what is heart rhythm disorder
Heart Rhythm Disorders Definition and Overview. A heart rhythm disorder is an abnormal variation from the normal heartbeat. Heart rhythm disorders involve abnormalities of one or more of the following: heart rate, regularity of beats, sites where electrical impulses originate, or sequence of activation of heartbeats.Heart rhythm disorder is also referred to as an arrhythmia.The primary function of the heart is to supply blood and nutrients to the body. The regular beating, or contraction, of the heart moves the blood throughout the body. Each heartbeat is controlled by electrical impulses traveling through the heart.he irregular beating results in a heart rhythm disorder, or arrhythmia. The electrical system regulating heartbeat consists of two main areas of control that are connected to a series of conducting pathways, similar to the electrical wiring in a house. 1  The sinoatrial, or SA, node is located in the right atrium.
Transcript: Arrhythmia, or heart rhythm disorder, is a general term for an irregular heartbeat. Most arrhythmias are not dangerous, but some may indicate serious underlying heart disease and some can lead to serious problems such as loss of consciousness, stroke and sudden cardiac death.n fact, about 2.2 million Americans have a type of arrhythmia called atrial fibrillation-and that is only one type of rhythm problem. Some arrhythmias can lead to serious problems, including heart disease, stroke or sudden cardiac death.
