Paediatric Cardiology is a specialty that piqued my interest when I started training in Paediatrics. In our day-to-day, congenital heart disease, paediatric cardiomyopathy and arrhythmia are a both diagnostic and therapeutic challenge. It is precisely this complexity that compels us to continue learning new diagnostic techniques and to invest time in research, which is key in advancing as professionals and improving the quality of care for our patients.
