Intracardiac electrophysiology study

The intracardiac electrophysiology study is the most precise examination for studying the electrical activity of the heart. It involves introducing fine catheters through a vein, usually at the groin crease, and positioning them inside the cardiac chambers in order to record the electrical signals directly at their source. This examination makes it possible to understand the exact origin of unexplained palpitations, dizzy spells or syncope, and to precisely characterise a rhythm disorder: location of the abnormal circuit, mechanism of the arrhythmia, response to stimulation. The physician can thus reproduce the arrhythmia under controlled conditions to analyse it more accurately. The electrophysiology study is often the first step of ablation treatment: when the circuit responsible for the arrhythmia is identified, it can be treated in the same session, avoiding a second procedure. At Clinique Pasteur Tunis, this examination is performed in a fully equipped electrophysiology laboratory dedicated to heart rhythm care, by a specialised team that supports the patient at every step.
