About the department

The department of arrhythmias and electrophysiology at Teknon Medical Center Barcelona specializes in diagnosing and treating patients with cardiac arrhythmias. The department comprises internationally recognized specialists and experts in diagnosing and treating any arrhythmias, who are the standards and pioneers in treating arrhythmias that cause sudden death. Clinical studies are constantly conducted based on the department, giving patients the latest treatment. An interdisciplinary approach allows diagnostics and treatment to be carried out comprehensively and holistically. The department has state-of-the-art equipment for all electrophysiology and instrumental medicine methods. Outpatient and inpatient admission is possible.

The medical team has exceptional experience in catheter ablation, implantation of pacemakers and defibrillates to prevent sudden cardiac death from lethal arrhythmias. The department's specialists regularly monitor implantable devices using remote technologies to ensure the safety of patients, wherever they are. In addition, there is a comprehensive ablation program that offers epicardial ablation to treat ventricular tachycardia and atrial fibrillation.
