Electrophysiological Study (EPS)
What is Electrophysiological Study (EPS)?
Electrophysiological Study (EPS) is an invasive procedure that can provide specific and detailed information on the abnormal heart rhythm (arrhythmia), which is more superior to some other non-invasive tests. We can base on the results of EPS and offer the most appropriate treatment such as drug therapy or catheter ablation. During an attack of abnormal heart rhythm, you may have palpitation, chest discomfort, dizziness or vertigo. Occasionally, this may result in heart failure or even sudden death.
Why is Electrophysiological Study (EPS) required?
Heart rhythm is mainly controlled by the conduction system of the heart. Any abnormality in the conduction system may result in abnormal heart rhythm (arrhythmia). EPS is a procedure to identify the underlying cause and mechanism of abnormal heart rhythm so that further appropriate treatment including drug therapy and catheter ablation can be provided.
