Telehealth is the use of electronic information and telecommunications technologies to support long-distance clinical health care, patient and professional health-related education, public health and health administration.

Technologies used in telehealth typically are: videoconferencing, the Internet, store-and-forward imaging, streaming media, and terrestrial and wireless communications. While new applications are increasingly found for using these technologies, significant barriers remain to making these technologies an integral part of daily health care practice.

In general, telemedicine refers to clinical services conducted via telehealth technologies.  Telehealth is used as an umbrella term that encompasses telemedicine applications.
