The scientific history of telemedicine dates back to ancient Greece, providing a comprehensive historical perspective of telemedicine to the present day, which has led to more than a century of innovation in technology and telemedicine care (

The World Health Organization (WHO) defines telemedicine as:
The delivery of health care services, where distance is a critical factor, by all health care professionals using information and communication technologies for the exchange of valid information for diagnosis, treatment, and prevention of disease and injuries, research and evaluation, and for the continuing education of health care providers, all in the interests of advancing the health of individuals and their communities (

Telemedicine is a remote diagnosis and treatment of patients through telecommunication technology (

5). Telemedicine is rapidly being integrated into health care as a way to increase patient access, particularly across the urban-rural divide (

Modern telemedicine applications originated in Europe by a Dutch physician, Willem Einhoven, with the remote transmission of electrocardiograms in 19051. In the 1860s, during the Civil War, the telegraph was used to relay messages from wounded soldiers to medical teams (

Following those developments, radio consultations were carried out for patients who were on ships at sea and on remote islands from medical centers in Norway, Italy, and France in the 1920s, 1930s, and 1940s. In the early 1950s, the transmission of radiographic images began in the United States, and similar experiments were conducted in Canada shortly thereafter (

Telemedicine applications and its benefits include remote consultation and diagnosis, specialized clinical care (including examples from anesthesiology, dermatology, cardiology, psychiatry, radiology, critical care, and oncology), and others (including examples from patient education, monitoring at home, and continuing education) (

(i) Where the sender and receiver are both online at the same point in time and "live" transmission of information occurs as real-time or synchronous telemedicine.
(ii) Where the sender stores and sends databases to the receiver at a suitable time, and the receiver can check the data as remote or asynchronous drug storage and supply.
(iii) The remote monitoring type of telemedicine (ie, self-monitoring) uses a range of technological devices to remotely monitor a patient’s health and clinical symptoms.
(iv) Health professional care, referral, and counseling services.
(v) Health professional to the patient (

Computing and information technologies, network infrastructures, and telecommunications are the main drivers of technological innovation. Also, the goals of technology initiatives that have helped the development of telemedicine include expanding access to health services and treatment, providing health care for travelers, military programs, remote home care, reducing costs, developing tools and health policies and strategies (

Accordingly, the importance of rapid medical services in accidents and war is the first level of activities. The purpose of developing and using telemedicine is to improve medical care for all defense sectors, especially the frontline medical forces.
