Electrocardiography or ECG can be easily transmitted with the help of wireless and telephone. This unique process was first done in the year 1958 by Barr who transmitted ECG tracings to nearly 40,000 feet. This process is also called as telecardiology. The teletransmission of ECG can be done using several indigenous methods. However one of the oldest telecardiology systems or the teletransmission of ECG to be recorded had been established in the Gwalior city of India in the year 1975 at the GR Medical College. It system was managed by Dr. S. Makhija, Dr. Ajai Shanker and P.K. Mantri who found out about this system with the help of different techniques for the first time.
This telecardiology system can enable wireless transmission of electrocardiograph from home of the patients or from a moving ICU van to the central station of the hospital in its ICU department of medicines. These transmissions that use wireless methods were done with the help of frequency modulations that completed eliminated noise. The transmission was also done using telephone lines. The electrocardiography output was basically connected to the telephone wire or input with the help of modulators that could easily convert ECG into quite higher sound frequency. However on the other hand a demodulator could easily reconvert the sound into ECG and with fine accuracy gain. This ECG is being converted to sound waves along with the frequencies which can vary from nearly 500 Hz to around 2500 Hz and with 1500 Hz as the baseline. This telecardiology system can also be used to monitor patients through peacemakers in rural areas. Moreover when this system was used in remote areas the central or base unit that has the ICU center was also able to correctly interpret the arrhythmia. Therefore this technology of telecardiology helped in reaching medicines even in rural and remote areas.
The benefits
When it comes to telecardiology in the form of telemedicine, it could be very beneficial to the populations living in remote regions and isolated communities. Moreover they are now being widely used in virtually all the medical domains. The specialties who use telemedicine generally use tele-prefix, in the form of telemedicine which is applied by radiologist which is known as teleradiology. In the same way the telemedicine which is applied by the cardiologists is called as telecardiology and this goes on for several other forms of treatment and types medical communications. Moreover telemedicine is also beneficial as a tool to communicate between the specialists available at remote location and the general practitioner at the main medical service center.
