Cardioneuroablation

A catheter-based approach for selected people with reflex fainting and documented cardiac pauses.

About cardioneuroablation

Pacemaker implantation

Stimulation of the heart to treat certain slow rhythms and electrical conduction blocks.

Understanding pacemaker implantation

Atrial fibrillation ablation

Catheter treatment to control atrial fibrillation in selected people.

Ablation and care for AF

Cardiac resynchronization device

Stimulation intended to coordinate the ventricles in selected cases of heart failure.

Indications for CRT-P and CRT-D

Cardioneuroablation was created by the Pachón group and described in 2005 in Europace. Read about the origin of the technique and studies in selected patients.

The origin of cardioneuroablation

Tilt test / Tilt table test

A test that evaluates how the autonomic nervous system responds to a change in body position, helping diagnose fainting or dizziness related to drops in blood pressure.

Implantable loop recorder

A small device implanted under the skin that monitors and records the electrical activity of the heart over long periods, helping detect rare or intermittent heart problems.

Electrocardiogram

A simple, noninvasive test that records the electrical activity of the heart, essential for diagnosing arrhythmias, heart attacks and other heart diseases.

Echocardiogram

An ultrasound test that evaluates the structure and function of the heart, providing detailed images of the heart chambers, valves and blood flow.

High-resolution electrocardiogram

A test that records the electrical activity of the heart in high definition, allowing more detailed detection of arrhythmias and other heart conditions.

Transesophageal cardiac pacing

A technique that uses a device implanted in the esophagus to stimulate the heart, indicated in cases of bradycardia or other heart rhythm disorders.

Additional tests

Additional tests are essential for accurately identifying heart problems and guiding the best treatment. In areas such as Exercise Medicine, cardiac device implantation, radiofrequency ablation and the treatment of atrial fibrillation...
