Electrophysiology is a study on the records of electrical activity inside the heart. One or more flexible wires with electrical conductors are threaded into heart to measure the electrical signals of it. Electrical currents can also be sent through the wires into the heart, this process is called as pacing. Abnormal rhythms can be triggered in the heart, which allows the physician to determine the abnormalities in heart rhythm. An electrophysiological study is an invasive procedure that evaluated abnormal heart rhythm disturbances. There are several ways & studies where Electrophysiology studies may help in diagnosing heart rhythm abnormalities. An abnormal rhythm may be deliberately stimulated by a doctor during the EP study so that the underlying problem can be identified. An abnormal heart rhythm can stimulate & evaluate the effectiveness of a drug used. The results of the electrophysiology studies would help the doctor determine further therapeutic measures, such as inserting a pacemaker or implantable defibrillator, adding or changing medications, performing additional ablation procedures, or providing other treatments. International Journal of Cardiovascular Research emerges as a best indexed journal with impact factor compared to other competitive journals focusing on electrophysiology 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.
