What is cardiac electrophysiology? Cardiac electrophysiology is
the study of the electrical system of the heart. It involves the
diagnosis and treatment of many different abnormalities that
result in changes in the heart’s rhythm, such as heartbeats that
are too fast, slow or irregular, and that result in symptoms
such as a racing heartbeat; heart palpitations; or fatigue,
dizziness, fainting; and sudden cardiac arrest . Cardiac
electrophysiology is a subspecialty of cardiology, and
specialists in cardiac electrophysiology are known as cardiac
electrophysiologists or electrophysiologists. Who are cardiac
electrophysiologists and what do they do? Cardiac
electrophysiologists are heart specialists trained to perform
studies in arrhythmia (uneven heart beat ) and implant devices
such as pacemakers and defibrillators to regulate heart rhythms.
They also perform minimally invasive surgical procedures such as
radiofrequency ablation (RFA) of aberrant electrical pathways
that cause heart rhythm abnormalities. What a
