Arrhythmia is defined as an irregular heartbeat.Phenomenon of heart beating too fast is tachycardia. Heart beating too slowly is bradycardia, beating too early is called premature contraction & too irregular is called fibrillation. Arrhythmias generally occur when the electrical impulses to the heart which coordinate heartbeats donot work properly which makes heart beat too fast/slow or inconsistently. Many heart arrhythmias are harmless. Every person experience irregular heartbeats in their life time, which may feel like fluttering. Some arrhythmias, however, especially if they veer too far from a normal heartbeat or result from a weak or damaged heart, may cause troublesome and even potentially fatal symptoms. Cardiology deals with disorders of the heart. Cardiology includes medical diagnosis and treatment of congenital heart defects, coronary artery disease, heart failure etc. Doctors or Physicians specialized in this field of medicine are called cardiologists & the Physicians specialized in cardiac surgery are called cardiac surgeons. International Journal of Cardiovascular Research emerges as a best indexed journal with impact factor compared to other competitive journals focusing Arrhythmia and other cardiology studies by bringing up the recent research to global scientific community through its publications. The papers submitted are undergone through perfect plagiarism checks, later peer reviewed by the expert group and published after through revisions. "
