About CardioNetworks

Welcome to

The CardioNetworks Foundation is a non-profit organization founded in 2007 and based in The Netherlands. The goals of the Foundation are: “to improve medical knowledge, especially in the field of cardiology, and to provide access to this knowledge by facilitating publications in digital or other form, amongst other means by building and maintaining websites.” All revenues are spent in the pursuit of this cause. The Dutch Tax Administration has designated the Cardionetworks Foundation as a Public Benefit Organisation (abbreviated in Dutch as ‘ANBI’). Gifts to the Cardionetworks Foundation can be tax deducted in the Netherlands (see Tax Administration for conditions).

CardioNetworks’ first project was, an online electrocardiography course.  We now publish and maintain around 30 individual websites in different stages of development, including and, online resources in echocardiology and intervention cardiology.  Our sites provide high quality, up-to-date information freely to physicians all around the world.
