What is transesophageal cardiac pacing (CETE)?
Transesophageal cardiac pacing (CETE) is an innovative method conceived and developed by Dr. Pachón. This test is used to identify supraventricular arrhythmias and can also be used to terminate sustained supraventricular tachycardia.
How is transesophageal cardiac pacing performed?
CETE is performed using a thin silicone electrode introduced through the nostril. Through this electrode, the heart's electrical activity can be recorded while the heart is stimulated. Pacing is provided by special equipment, while recording is performed using a computerized electrocardiogram developed specifically for this test by Dr. Pachón himself.
The test is well tolerated and lasts an average of 30 minutes. To undergo it, the patient needs to fast for 4 hours and wear a shirt that opens at the front to facilitate the electrocardiogram connection. During the procedure, patients with tachycardia may experience controlled tachycardia, which will be recorded and immediately terminated by the equipment, allowing an accurate diagnosis.
Main indications:
- Patients with palpitations or tachycardias not yet diagnosed.
- Patients with suspected dysfunction of the natural pacemaker.
- Patients with undiagnosed dizziness or syncope.
- Termination of sustained supraventricular tachycardia.
The test is performed on an outpatient basis, so hospital admission is not required. At the end, the patient can eat normally and return home. Patients taking antiarrhythmic medications should consult their physician to assess whether medication needs to be stopped before the test to avoid interference with results. A detailed report will be issued and provided to the requesting physician, who can advise on the best treatment to follow.
