Arrhythmia is a medical problem with the rate or rhythm of the heartbeat. Heart may beat too fast, sloe or irregular rhythm during arrhythmia. A heartbeat that is too fast is called tachycardia. A heartbeat that is too slow is called bradycardia. Arrhythmias can be serious or life threating but usually are harmless. During an arrhythmia, the heart may not be able to pump enough blood to the body. Lack of blood flow can damage the brain, heart, and other organs. A journal is a periodical publication intended to further progress of science, usually by reporting new research. Most journals are highly specialized, although some of the oldest journals publish articles, reviews, editorials, short communications, letters, and scientific papers across a wide range of scientific fields. Journals contain articles that peer reviewed, in an attempt to ensure that articles meet the journal's standards of quality, and scientific validity. Each such journal article becomes part of the permanent scientific record.
