Transesophageal electrophysiologic study (TEEPS) is a medical procedure used to evaluate and diagnose certain heart rhythm abnormalities, also known as arrhythmias. It involves the insertion of a specialized catheter through the esophagus to directly evaluate the electrical activity of the heart.
During a TEEPS, the patient is typically placed under sedation to ensure comfort. An electrode-tipped catheter is then carefully inserted through the mouth, down the throat, and into the esophagus. This catheter contains sensors that can measure the electrical signals produced by the heart. These signals provide valuable information about the heart's rhythm, its conduction system, and any associated abnormalities.
The primary purpose of a TEEPS is to determine the location and nature of any electrical disturbances within the heart. It can help identify the presence and causes of various arrhythmias, such as atrial fibrillation, ventricular tachycardia, or atrioventricular block. By directly assessing the heart's electrophysiological properties, healthcare providers can make informed decisions regarding suitable treatment options.
TEEPS may also be used to assist in guiding certain interventions, such as catheter ablation, a procedure that aims to correct abnormal electrical pathways in the heart. Additionally, it can help evaluate the effectiveness of prescribed anti-arrhythmic medications.
In conclusion, a transesophageal electrophysiologic study is a diagnostic procedure that involves the insertion of a specialized catheter through the esophagus to directly assess the electrical activity of the heart. It aids in identifying and diagnosing various heart rhythm abnormalities, informing treatment decisions, and guiding specific cardiac interventions.
