The means of Telemedicine is simply stated in the word itself. Telemedicine combines electronic or digital technology with medical treatments. It also allows health care providers to communicate with patients from across the world, rural areas, and within the home. This communication is made possible through the use of transmission of videos, images, video conferences, medical records, and audio interface. Telemedicine can be applied in a numerous healthcare fields such as psychiatry, radiology, cardiology, and many others. Telemedicine, surprisingly is not a new invention. It has existed in the form of telephone and fax machines. However today it has expanded vastly due to the advancement of technology and can be catered to rural areas. “Today, telemedicine is a combination of advances in medical technologies; the use of computers; the use of databases to store and retrieve information ("Informatics"); high-speed telecommunication facilities; and mainstream medical procedures.”

Telemedicine can be performed in two ways which are real time or store and forward. Real time is when the information is processed and feedback is required. However, real time or store forward is when the information can be stored in a hub and retrieved at a later time. The two types of transmission equipment used are satellite and terrestrial. Satellite transmission is capable of transmitting the most information with the best quality. Terrestrial equipment however transmits information through fiber optics, copper cables, and microwaves. The modes of transmission are in either analog or digital. Analog is in the form of waves such as television and produces high quality images due to the satellite equipment. The digital mode which is most widely preferred, transmits information in bits. The CODEC system is used for transmission of cardiac images. The CODEC translates the analog form (picture) of the image to a digital form and transfers the image again for viewing on the monitor. This process requires a web camera, speakers, and monitors from both ends. The process of telemedicine combines computer capabilities for the greater cause of human existence.
