Healthcare changed tremendously over the past decades due to the availability and use of technical innovations. The technical support options for diagnosing and managing patients increase by the day and are partly driven by several factors, including the availability of good Internet connection in most Western European regions, storage of all medical data in electronic patient records, and accessibility of most patients to a smartphone, tablet, or computer. Current challenges in healthcare, such as an increase in chronic patients caused by aging of the population, lack of staff, and increasing costs also speed up these technical developments because they are expected to reduce the negative impact of these challenges. Terms such as eHealth, digital health, telehealth, telemedicine, and telemonitoring are often used, and for healthcare professionals it can be difficult to see the forest through the trees. In this paragraph, a pragmatic overview of these concepts will be provided with an explanation. These will be illustrated with examples from scientific literature.
