Henrick Joan Joost (Hein J. J. ) Wellens, M.D., (1935–2020) was a Dutch cardiologist who is considered one of the founding fathers of clinical cardiac electrophysiology - a discipline which enables patients with cardiac arrhythmias to have catheter electrode mapping and ablation. Wellens was known among European cardiologists as "the giant of Maastricht" and for many years was associated with the University of Limburg School of Medicine in Maastricht, Netherlands.
