Intracardiac electrophysiology study (EPS)

Electrophysiology study - intracardiac; EPS - intracardiac

The exact location and type of the arrhythmia may be determined so that specific therapy can be applied appropriately. The arrhythmia may originate from any area of the heart's electrical conduction system.

For example:

• Sick sinus syndrome occurs when the SA node of the heart malfunctions.
• Wolff-Parkinson-White syndrome happens if you have an extra electrical pathway leading to avoidance of the normal path through the AV node.
• Ventricular fibrillation and ventricular tachycardia are 2 arrhythmias that occur if muscle cells in the ventricles inappropriately take over the electrical activity of the heart.
