Cardiac Electrophysiology is a subspecialty of [[cardiology]] focused on diagnosing and treating electrical activities of the heart, or heart rhythm disorders, known as arrhythmias.
{{DISPLAYTITLE:Cardiac Electrophysiology}}
=== Overview ===
== Overview ==
The field of Cardiac Electrophysiology is concerned with understanding the electrical properties and conduction system of the heart. Electrophysiologists are involved in the assessment and management of complex arrhythmias, implantation and management of pacemakers and defibrillators, and ablation of arrhythmias.

'''Cardiac electrophysiology''' is the study of the electrical properties and conduction pathways of the heart. It encompasses the understanding of the heart's electrical system, which is crucial for maintaining normal heart rhythm and function. The field involves the diagnosis and treatment of [[arrhythmias]], which are disorders of the heart rate or rhythm.
== Cardiac Electrophysiology Tests ==
== Electrical Conduction System ==
Cardiac Electrophysiology studies (EPS) are performed to assess the heart's electrical system and to diagnose abnormal heartbeats or arrhythmia. The most common test is the EP study, which is invasive and involves the insertion of catheters and wire electrodes through blood vessels into the heart chambers. This allows physicians to measure electrical activity and identify any disturbances in the heart's rhythm.
The heart's electrical conduction system is responsible for generating and propagating electrical impulses that trigger heartbeats. The main components of this system include:
== Clinical Cardiac Electrophysiologist ==
* The [[sinoatrial node]] (SA node), which is the natural pacemaker of the heart.
A clinical cardiac electrophysiologist, often referred to as a cardiac EP, is a [[physician]] who has received extensive training in the management of heart rhythm disorders. They are cardiologists who have pursued additional specialization in electrophysiology and are skilled in procedures such as catheter ablation and the implantation of cardiac rhythm management devices.
* The [[atrioventricular node]] (AV node), which acts as a gatekeeper, regulating the electrical impulses between the atria and ventricles.
* The [[bundle of His]], which transmits impulses from the AV node to the ventricles.
* The [[Purkinje fibers]], which distribute the electrical impulse throughout the ventricles, causing them to contract.
== Procedures and Treatments ==
== Electrophysiological Studies ==
Cardiac electrophysiologists perform various procedures, including:
Electrophysiological studies (EPS) are tests that help doctors understand the nature of abnormal heart rhythms. During an EPS, catheters are inserted into the heart through blood vessels to record electrical activity and to stimulate the heart to reproduce arrhythmias under controlled conditions.
* '''[[Catheter ablation]]''': A minimally invasive procedure to treat arrhythmias.
* '''[[Pacemaker implantation]]''': A device implanted to regulate slow heart rhythms.
* '''[[Implantable Cardioverter Defibrillator (ICD)]]''': A device designed to prevent sudden death from cardiac arrest due to life-threatening arrhythmias.
* '''[[Cardiac Resynchronization Therapy (CRT)]]''': A treatment for heart failure that helps the ventricles contract more normally.
== Training and Certification ==
== Common Arrhythmias ==
Cardiac electrophysiologists undergo extensive training, including medical school, residency in internal medicine, fellowship in cardiology, and additional fellowship in electrophysiology. They are certified by boards such as the [[American Board of Internal Medicine]] (ABIM) with a subspecialty certification in Clinical Cardiac Electrophysiology.
Some common types of arrhythmias include:
