Dr. Giovanni Battista Forleo, MD, PhD.

Affiliation: Dr. Giovanni B Forleo received his Medical Degree at the University of Florence, Italy. Subsequently he completed his Residency at the Catholic University in Rome. After the clinical fellowship, he obtained the PhD and has been appointed Adjunctive Professor at the University of Rome “Tor Vergata”. Dr. Forleo currently serves as cardiac electrophysiologist at the University Hospital of Tor Vergata in Rome. His major area of research is related to cardiac pacing and electrophysiology. His research work has been published in a variety of international journals and was presented in many international conferences.

Dr. Fiorenzo Gaita, MD.

Affiliation: Full Professor in Cardiology at the Department of Medical Sciences, University of Turin, Italy. His field of interest has focused on clinical arrhythmias and transcatheter ablation techniques. Above all, in the last thirty years, he pioneered this field directly contributing to the first transcatheter ablation by DC shock carried out in Europe, the first surgical ablations for accessory pathways and the percutaneous ablation techniques of nodal reentrant tachycardias.
