EP Fact Sheet
What is electrophysiology?
Electrophysiology is a cardiology specialty that deals with the diagnosis and treatment of heart
rhythm disorders, which are problems related to the heart’s electrical system. The heart’s
electrical system is responsible for creating the signals that trigger the heart to pulse or beat.
Abnormal heart rhythms (arrhythmias) are caused by
problems with the electrical system that regulates the
steady heartbeat. The heart rate may be too slow or too
fast; it may stay steady or become chaotic (irregular).
Some arrhythmias are very dangerous and cause sudden
cardiac death (SCD), while others may be bothersome
but not life threatening.
The Three Ps of the Heart
The heart has three main
components:
Millions of people experience arrhythmias at some point
in their lives. Most of the time, they are harmless and
happen in healthy people free of heart disease. However,
some abnormal heart rhythms can be serious or even
deadly. Having other types of heart disease can also
increase the risk of arrhythmias.
1. The Pump: The main
muscular mass of the heart.
2. The Pipes: The “plumbing” of
the heart where blood flows
through all the arteries.
3. The Pulse: The “electrical”
system of the heart
responsible for the pumping
action, or “heartbeat.”
Electrical disorders include, but are not limited to, atrial
fibrillation (AF) (the most common arrhythmia), ventricular
fibrillation, long QT syndrome, sinus tachycardia and
syncope (fainting).
Electrophysiologists focus on
problems with the heart’s
electrical system and treating
heart rhythm disorders.
What is an electrophysiologist?
An electrophysiologist is a special type of heart doctor that treats patients with heart rhythm
problems. Electrophysiologists are cardiologists with advanced medical training that detect,
diagnose and treat problems with the heart’s electrical system which result in heart rhythm
disorders. The electrophysiologist can also help you learn if you or your family members are at
risk for life threatening arrhythmias.
An electrophysiologist is commonly called a heart rhythm specialist or EP.
