Cardiac Electrophysiology

Heart Arrhythmia Studies in LA County

Abnormal heartbeats are called arrhythmia. This condition is characterized by strange electrical impulses that cause the heart to beat too fast or too slow. Electrophysiology studies (EPS) are exams that discern the details of an irregular heartbeat and help the doctor determine what can be done to treat it.

You may want to be in need of an EPS if:

• You often have fluttering feeling in your chest
• You experience a rapid heartbeat at random times
• You have frequent chest pains and shortness of breath
• You suffer from unexplained fainting spells
• You recently suffered a heart attack and notice your heartbeat is off

What Happens During an EPS

An EPS is a minor surgery and you should prepare for it the same way you do many other operations. This includes fasting after midnight before the operation, asking your doctor if you can still take your regular medication beforehand, and having someone who can drive you to and from the hospital.

A nurse will administer a sedative through an IV. This is meant to relax you but will not necessarily put you to sleep. Staying awake is beneficial as the doctor will probably want to ask you some questions during the test. A small incision is made in the groin area where a doctor will insert catheters and weave them through a vein to the heart.

Electrical pulses are emitted through the catheter that stimulates the heart into beating at desired speeds. The catheters will record these signals and the resulting information should tell the doctor where the irregular heart beat is coming from.

The Aftermath

If an EPS is done when it is already known that you have an arrhythmia, the doctor may try to treat the condition right there through an ablation procedure. In ablation, radio waves are emitted through a catheter that targets and destroy damaged tissue responsible for the arrhythmia.

EPS's are mostly used for diagnostic purposes and not treatment. When the operation is over the medical team will patch you up and discuss the results with you. The doctor will tell you their recommended treatment for the condition, which may involve medication or undergo another operation.
