At the beginning of 2012, he passed the specialist exam in internal medicine, after which he started a subspecialization in cardiology as a department doctor at the Institute for Intensive Cardiac Care, Arrhythmias, and Transplant Cardiology. In the same year, he received the scholarship "Stevo Julius Visiting Scholar Award" and carried out his arrhythmological training with the greats of world rhythmology - Prof. Jalife (basic science) and Prof. Morady (Clinical Arrhythmology) at the Center for Arrhythmia Research, University of Michigan, Ann Arbor, USA. in 2014 receives a scholarship from the European Society for Arrhythmology (EHRA advanced EP fellowship) and spends a year of subspecialization in advanced arrhythmology and catheter ablation at the university hospital in Brussels (UZ Brussel – Vrije Universiteit Brussel) with prof.
