The invention of telegraphs and telephones advanced Telemedicine towards what it is today. They made long-distance communication easier, increased the speed of delivery and were being used by the common public on a large scale. Due to this, it was used by the military during the Civil War for ordering medical supplies as well as communicating deaths or injuries on the battlefield.
Early Telemedicine usage cited is back in 1940s Pennsylvania, when radiology images were sent using telephone line between two towns 24 miles. This probably was the world’s first example of an electronic medical record transfer. It was further enhanced by a Canadian doctor in the 1950s, into a teleradiology system. In 1959, the University of Nebraska set up a two-way television to transmit information to medical students and later linked the system with a state hospital for video consultations. The University of Miami School of Medicine in 1967 worked with the local fire department in 1967 to transmit ECG rhythms in rescue situations over the radio to Jackson Memorial Hospital.
The world became more connected with the widespread use of telephones. Physicians could give their patients medical advice over the phone as well as confer with other physicians to exchange information. With the advanced communication methods used today telephones may not seem significant, but they played an essential part in the evolution of Telemedicine.
