Electrophysiological Study (EPS) | Cardiac Arrhythmia Diagnosis | MediHeart Medical Center Güzelyurt
Electrophysiological Study (EPS) is an interventional cardiology procedure performed to determine the cause of heart rhythm disorders and plan appropriate treatment. For whom is EPS performed, how is it done, and what is the treatment process like? Get detailed information with the evaluations of Prof. Dr. Osman Beton.
Electrophysiological Study (EPS)
Heart rhythm disorders (arrhythmias) can occur as a result of changes in the heart’s normal electrical conduction system. Complaints such as palpitations, a sensation of irregular heartbeat, dizziness, fainting, or unexplained rapid heartbeats can negatively affect daily life and may require detailed evaluation in some cases. Since not every rhythm disorder develops due to the same underlying cause, establishing the correct diagnosis is of great importance in determining the treatment to be applied. Electrophysiological Study (EPS) is one of the advanced interventional cardiology methods used to examine the heart’s electrical conduction system in detail.
During EPS, thin electrophysiology catheters are advanced through a blood vessel into specific regions of the heart, and the electrical activity of the heart is recorded in detail. In this way, the region from which the rhythm disorder originates, how it occurs, and which treatment method may be appropriate can be evaluated. When necessary, therapeutic interventions such as catheter ablation can also be planned in the same session. However, this decision is made entirely based on the patient’s clinical findings and the data obtained during the procedure.
At MediHeart Medical Center Güzelyurt Cardiology Department, the Electrophysiological Study (EPS) is planned by our Cardiology Specialist Prof. Dr. Osman Beton in line with the patient’s complaints, ECG findings, rhythm recordings, and detailed cardiological evaluation. The aim is not only to detect the rhythm disorder, but also to determine the most appropriate treatment approach.
What is an Electrophysiological Study (EPS)?
An Electrophysiological Study is a diagnostic interventional cardiology procedure that directly examines the heart’s electrical conduction system. The natural electrical pathways inside the heart are evaluated through specialized catheters, and the mechanism behind the formation of the rhythm disorder is analyzed in detail.
Standard ECG or Holter recordings may not be sufficient to show certain rhythm disorders. EPS is one of the important methods that can help establish a detailed diagnosis, especially in arrhythmias that develop intermittently or whose cause cannot be clearly determined.
Who Can Undergo an Electrophysiological Study?
EPS is not performed on every patient presenting with palpitations. First, a detailed cardiological evaluation of the patient is conducted to determine whether an interventional examination is necessary.
An Electrophysiological Study can be evaluated in the following situations:
Unexplained episodes of palpitations
Recurrent supraventricular tachycardia (SVT)
Suspected Wolff-Parkinson-White (WPW) syndrome
Certain ventricular rhythm disorders
Unexplained fainting (syncope)
Patients in whom the source of the rhythm disorder needs to be identified prior to treatment planning
The final decision is made as a result of the evaluation performed by the cardiology specialist.
What Tests Are Performed Before an Electrophysiological Study?
Prior to the procedure, the patient’s overall cardiovascular condition is evaluated in detail. This increases procedural safety and allows for assessing how the obtained data will contribute to the treatment plan.
The following examinations may be performed when deemed necessary:
Cardiology examination
Electrocardiography (ECG)
Holter rhythm recording
Echocardiography
Blood tests
Exercise stress test or advanced imaging methods when necessary
Thanks to these evaluations, potential causes of the rhythm disorder are investigated and procedural planning is carried out.
How is an Electrophysiological Study (EPS) Performed?
The procedure is generally performed by entering through a vein in the groin area. Thin electrophysiology catheters are advanced through the blood vessel into the heart and placed in different regions of the heart. Electrical signals are recorded with the help of the catheters, and the mechanism of the rhythm disorder is evaluated by delivering controlled electrical impulses.
With the findings obtained, the region from which the rhythm disorder originates, how the conduction pathways function, and the suitability of treatment options can be determined. In suitable patients, provided it was planned in advance and deemed necessary during the procedure, catheter ablation can be applied in the same session to treat the focus causing the rhythm disorder.
The duration of the procedure may vary depending on the type of rhythm disorder, the scope of the examination to be performed, and whether additional treatment is required.
Advantages Provided by an Electrophysiological Study (EPS)
An Electrophysiological Study (EPS) is one of the most detailed diagnostic methods in evaluating heart rhythm disorders. It can provide important information, especially in rhythm disorders whose cause cannot be fully determined by standard ECG, Holter, or other diagnostic tests.
In suitable patients, thanks to EPS:
The source of the rhythm disorder can be identified.
The heart’s electrical conduction system can be evaluated in detail.
The most appropriate treatment method can be planned.
Whether catheter ablation is required can be evaluated.
Unnecessary medication use can be helped to be prevented.
Diagnosis and treatment can be carried out in the same session in certain patients.
However, it cannot be guaranteed that the same results will be obtained in every patient. The expected benefit from the procedure may vary according to the type of rhythm disorder, underlying heart disease, and overall health status of the patient.
Are There Risks to an Electrophysiological Study?
EPS is considered among safe interventional cardiology procedures when performed by experienced teams. Nevertheless, as with any interventional procedure, certain risks cannot be completely eliminated.
Bleeding at the entry site, bruising, vessel-related complications, temporary rhythm changes, or other rare complications may develop during or after the procedure. All potential risks are explained to the patient in detail before the procedure, and necessary safety measures are taken.
The goal in treatment planning is to determine the most appropriate approach for the patient by evaluating the diagnostic or therapeutic benefit provided by the procedure alongside potential risks.
Post-Procedure Recovery Process
After the Electrophysiological Study is completed, patients are kept under observation for a specific period. Discharge time may vary depending on the access site used during the procedure and the general health status of the patient.
It is important to protect the entry site, avoid heavy physical activities for the duration recommended by the physician, and take prescribed medications regularly. Follow-up appointments should not be missed, and healthcare facilities should be consulted without delay in case of unexpected complaints that may develop after the procedure.
For patients who undergo catheter ablation, the follow-up plan can be arranged separately according to the scope of the procedure performed.
The Importance of Experience in Electrophysiological Studies
Accurate evaluation of heart rhythm disorders is possible not only with advanced technological equipment, but also with an experienced electrophysiology team. Correct analysis of the mechanism of the rhythm disorder, making the appropriate treatment decision, and planning catheter ablation when necessary require specialized expertise.
At MediHeart Medical Center Güzelyurt Cardiology Department, Prof. Dr. Osman Beton decides on the necessity of an Electrophysiological Study (EPS) by evaluating the patients’ clinical findings, ECG recordings, Holter results, and other cardiological examinations together. Creating a personalized diagnostic and treatment plan for every patient is adopted as the fundamental approach.
Frequently Asked Questions
Is an Electrophysiological Study (EPS) a painful procedure?
The procedure is performed under local anesthesia. Mild pressure may be felt during the placement of catheters, but the majority of patients tolerate the procedure comfortably.
Is EPS a surgery?
No. An Electrophysiological Study is not open-heart surgery. It is an interventional cardiology procedure performed through a blood vessel using thin catheters.
Is a rhythm disorder induced during EPS?
Yes. The goal of the procedure is to induce the rhythm disorder with controlled electrical stimulation and safely evaluate its mechanism. This procedure is performed under continuous monitoring.
Can catheter ablation be performed on the same day?
In suitable patients and provided it was planned in advance, catheter ablation can be applied in the same session following the Electrophysiological Study. This decision is made in accordance with the findings obtained during the procedure.
When can one return to daily life after the procedure?
The majority of patients can return to their daily lives within a short period. However, recommendations of the physician regarding protection of the access site and physical activity must be followed.
