"Atrial fibrillation is a common sustained heart rhythm disorder. Atrial fibrillation is mainly associated with stroke & heart failure which leads to death of the patient.Atrial fibrillation occurs because of an abnormality of the electrical signalling pathway Majority of Atrial fibrillation events are symptomless. So, it is important to ensure that doctors understand atrial fibrillation & its consequences. Atrial fibrillation is defined as a tachy-arrhythmia which is characterized predominantly by uncoordinated atrial activation. The AV node will not be in a condition to filter signals coming from the atria. This happens because the signals may be too fast, chaotic and irregular in nature. This will lead to inadequate emptying of the atria. Evaluation of scientific, academic, or professional work by others working in the same field.

International Journal of Cardiovascular Research emerges as a best indexed journal with impact factor compared to other competitive journals focusing Atrial fibrillation 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. "
