Dentro de la especialidad médica de cardiólogos, está el especializado en la electricidad del corazón. Por esto, cuando un médico nota que el órgano que está al lado del corazón no está en su máxima capacidad, para hacer contraer al corazón, el cardiologo lo dirige a un especialista en la corriente eléctrica del corazón, o sea, a un electrofisiólogo.
Dice la enciclopedia:
La
electrofisiología cardíaca es la
ciencia de los mecanismos, funciones, y desempeño, de las actividades
eléctricas de las regiones específicas del
corazón.
Este término es generalmente usado en describir estudios de tales
fenómenos por medio de grabación (intracardiaca) invasiva de la
actividad espontánea así como de respuestas cardiacas a la
estimulación eléctrica programada.
Un especialista en electrofisiología cardíaca es conocido como un
electrofisiologista cardiaco, o (más comúnmente) simplemente un
electrofisiologista. La electrofisiología cardiaca es considerada una
subespecialidad de la
cardiología,
y en la mayoría de los países requiere dos o más años de entrenamiento
de subespecialidad más allá de una especialidad general de cardiología.
Son entrenados para realizar procedimientos cardíacos interventionales
EP así como para implantaciones quirúrgicas de dispositivos.

http://en.wikipedia.org/wiki/Electrical_conduction_system_of_the_heart
The normal electrical conduction in the heart allows the impulse that is generated by the
sinoatrial node (SA node) of the
heart to be propagated to (and stimulate) the
cardiac muscle
(myocardium). The myocardium contracts after stimulation. It is the
ordered stimulation of the myocardium that allows efficient contraction
of the heart, thereby allowing
blood to be pumped throughout the body.
Signals arising in the
SA node (located in the
right atrium) stimulate the atria to contract and travel to the
AV node, which is located in the interatrial septum. After a delay, the stimulus diverges and is conducted through the left and right
bundle of His to the respective
Purkinje fibers for each side of the heart, as well as to the endocardium at the apex of the heart, then finally to the ventricular epicardium.

Cardiac electrophysiology is the
science of elucidating, diagnosing, and treating the electrical activities of the
heart.
The term is usually used to describe studies of such phenomena by
invasive (intracardiac) catheter recording of spontaneous activity as
well as of cardiac responses to
programmed electrical stimulation (PES). These studies are performed to assess complex
arrhythmias, elucidate symptoms, evaluate abnormal
electrocardiograms, assess risk of developing arrhythmias in the future, and design treatment.
A specialist in cardiac electrophysiology is known as a cardiac
electrophysiologist, or (more commonly) simply an electrophysiologist.
Cardiac electrophysiology is considered a subspecialty of
cardiology in most countries and usually requires two or more years of
fellowship training beyond a general cardiology fellowship. In early 2011, the
Centers for Medicare and Medicaid Services
(CMS) promoted cardiac electrophysiology to its own specialty category
in the United States. Cardiac electrophysiologists are trained to
perform interventional cardiac electrophysiology studies (EPS) as well
as surgical device implantations.

Cardiac electrophysiology is a relatively young subdiscipline of
cardiology and internal medicine. It was developed during the mid-1970s
by
Hein J. J. Wellens, professor of medicine at the
University of Maastricht in the
Netherlands and attending cardiologist at the Academic Hospital in
Maastricht.
Author of the definitive
English language textbook in the field is
Mark E. Josephson, formerly Robinette Professor of Medicine and chief of cardiology at the
University of Pennsylvania School of Medicine in
Philadelphia, Pennsylvania, now professor of medicine at
Harvard Medical School and attending cardiologist at
Beth Israel Deaconess Medical Center in
Boston, Massachusetts.

The
Heart Rhythm Society,
founded in 1979, promotes education and advocacy for cardiac arrhythmia
professionals (including cardiac electrophysiologists) and patients. It
is the largest society in the field.
