Prof. dr. F.C. (Frans) Visser is a Dutch cardiologist and researcher. He studied Medicine at the Leiden University and graduated in 1977. His cardiology training was in VU Medical Center (VUMC) Amsterdam, Netherlands, and registered as a cardiologist in July 1982. Cardiologist and Professor by special appointment at VUMC in Amsterdam, and acting tutor at the cardiology A study at VUMC. An university lecturer Chair regarding myocardial metabolism in cardiac failure. Since 2008 working in the independent treatment center Cardiozorg, Hoofddorp. Initially cooperating with the CFS/ME Medical Center in Amsterdam, an area of interest arose alongside cardiology in chronic fatigue syndrome. His research interests include exercise limitation, orthostatic intolerance, and dysautonomyia.
