Electrophysiology [2] is the branch of physiology that pertains broadly to the flow of ions (ion current) in biological tissues and, in particular, to the electrical recording techniques that enable the measurement of this flow. Classical electrophysiology techniques involve placing electrodes into various preparations of biological tissue. The ...
Cardiac electrophysiology is a branch of cardiology and basic science focusing on the electrical activities of the heart. The term is usually used in clinical context, to describe studies of such phenomena by invasive (intracardiac) catheter recording of spontaneous activity as well as of cardiac responses to programmed electrical stimulation ...
Clinical cardiac electrophysiology (also referred to as cardiac electrophysiology or simply EP), is a branch of the medical specialty of cardiology concerned with the study and treatment of rhythm disorders of the heart. [1] Cardiologists with expertise in this area are usually referred to as electrophysiologists.
Clinical electrophysiology is the application of electrophysiology principles to medicine. The two main branches of this discipline are electrotherapy and electrophysiologic testing (EEG, electromyography, etc.) Clinical electrophysiology can be utilized in the study and treatment of various physiological conditions, and most notably in clinical cardiac electrophysiology.
An EP study is typically performed in an EP lab or cath lab. These are specially equipped operating rooms that usually contain an X-ray machine capable of acquiring live X-ray video images (a fluoroscope ), equipment to record electrical signals from the heart, a stimulator to electrically excite the heart and control the heart rate, and ...
Clinical Electrophysiological Testing is based on techniques derived from electrophysiology used for the clinical diagnosis of patients. There are many processes that occur in the body which produce electrical signals that can be detected. Depending on the location and the source of these signals, distinct methods and techniques have been ...
The FDIC is an independent government agency charged with maintaining stability and public confidence in the U.S. financial system and providing insurance on consumer deposit accounts.
During local field potential recordings, a signal is recorded using an extracellular microelectrode placed sufficiently far from individual local neurons to prevent any particular cell from dominating the electrophysiological signal.
