  Electrophysiology - Wikipedia, the free encyclopedia
Electrophysiology is the study of the electrical properties of biological cells and tissues.
It involves measurements of voltage differences across cell membrane, and studies of how the flow of electrical current across membranes is regulated.
There are two major divisions of electrophysiology: intracellular recording and extracellular recording.

 Cardiac electrophysiology - Wikipedia, the free encyclopedia
Cardiac electrophysiology is the science of the electrical conduction system of the heart.
It is concerned with the normal and abnormal transmission of impulses from the cardiac pacemaker and its influence on contraction of the myocardium (the muscle of the heart).
Cardiac electrophysiology is considered a subspecialty of cardiology, and requires one or more years of fellowship training beyond a general cardiology fellowship.

 Cardiac Electrophysiology Laboratory
Cardiac electrophysiology is a medical specialty devoted to the diagnosis and treatment of abnormal heart rhythms.
Because there are some small risks of invasive electrophysiology procedures, they are generally only performed in the case of potentially life-threatening ventricular tachyarrhythmias, or in patients with problematic and medically refractory supraventricular tachyarrhythmias that are significantly affecting the patient's quality of life.
While modern electrophysiology laboratories may look imposing with all the computers and machinery, in reality the primary goal of any EP laboratory is efficient and successful performance of the EP procedure under the safest and most comfortable conditions possible.

 Comprehensive Cardiovascular Care Group:Electrophysiology Study
Because many arrhythmias occur sporadically, the goal of an electrophysiology study is to reproduce the arrhythmia so that it can be identified and treated.
Performed in the electrophysiology laboratory with the patient awake or mildly sedated and under constant monitoring (blood pressure and heart rate/rhythm), these studies involve inserting catheters into peripheral veins and threading them to various positions in the heart.
Since many arrhythmias occur sporadically, the goal of an electrophysiology study is to duplicate and then evaluate the arrhythmia in a controlled setting.

Electrophysiology testing includes a battery of tests which can be used to provide information about the visual system beyond the standard clinical examination of the eye.
The data are used in conjunction with the clinical examination and other tests (perimetry, dark adaptometry) to establish the correct diagnosis.
There is currently an effort to standardize electrophysiology testing throughout the world so that data collected in one laboratory can be used by others.

Therefore, an understanding of basic electrophysiology is fundamental to appreciating the function and dysfunctions of neurons, neural systems, and the brain.
Finally, a significant advantage of the in vivo preparation for electrophysiology is that it is more readily correlated with anatomical studies than in in vitro models.
For other examples of the use of behavioral electrophysiology to decipher the neurobiology of cognition, the reader is referred to work by Goldman-Rakic and colleagues (47) and by Wise, Desimone, and colleagues (48, 49).
