Electrophysiological Testing of the Heart
What is the test?
If you have an arrhythmia (abnormal heart rhythm), cardiologists can use an electrophysiologic study (EPS) to find out what part of the heart is causing this change in rhythm and what medicines will work best to bring that rhythm back to normal.

Ablation uses radiofrequency waves (like microwaves) to destroy a very small area of heart tissue to stop the arrhythmia from happening.
How do I prepare for the test?
