ECGs, or electrocardiographs, can be transmitted
using telephone and wireless. Willem
Einthoven , the inventor of the ECG,actually did tests with transmission of ECG via telephone lines. This was because the hospital did not allow him to move patients outside the hospital to his laboratory for testing of his new device.
In 1906, Einthoven came up with a way
to transmit the data from the hospital directly to his lab.
One of the oldest known telecardiology systems for teletransmissions of ECGs was established in Gwalior, India in 1975 at
GR Medical College by Dr. Ajai Shanker,
Dr. S Makhija, and Dr. P K Mantri using
an indigenous technique for the first time in India.
This system enabled wireless transmission of ECG from the moving
ICU van or the patient’s home to the central station in ICU of the department of Medicine. Transmission using wireless was done using frequency modulation,which eliminated noise. Transmission was also done through telephone lines.
The ECG output was connected to the telephone input using a modulator, which converted ECG into high-frequency sound. At the other end, a demodulator reconverted the sound into ECG with good gain accuracy. The ECG was converted to sound waves with a frequency varying
from 500 Hz to 2500 Hz with 1500 Hz at baseline.
ExpressECG in India
This case is an analysis of the implementation of ICT in the field of
medicine with specific reference to Life Care Institute of Medical Science and Research for telemedicine project named ExpressECG in remote area of Gujarat, which is spread across 12 districts in Gujarat in India. The organization decided to implement the teleechochardiography project for the remote and rural areas where ECG for heart patient is required and is unavailable due to any circumstances. Administrative personnel and doctors were interviewed for getting the firsthand experience of managing this project.
One live case is used as an illustration to analyze the operation of telemedicine.
The ExpressECG project, there is a central room that has various facilities like ECG machine, roaming broadband services, printer, phone lines, and 24 hours availability of the technicians. They are connected to remote area general practitioners and expert doctors. Required ECG hardware is built by EDS and the software is developed by Concepts India Pvt.Ltd
The application is developed on Client server architecture, where the software is installed at server side as well as client side having thin client architecture. The ECG taken of the patient is converted to digital signals using bio signal amplifier and stored in the computer, which is then transmitted to the expert doctor. Where the doctor can read the data and give his expert opinion after viewing the ECG. He sends his report back to the technician’s machine using Internet facility. Then a technician takes the print of the report and the ECG,
which is then converted in .jpg file for print and gives to the respective person or medical professional.
ECG machine is a 12-lead machine with a biosignal amplifier to convert the echocardiogram in to the digital format. The hardware is developed with high-noise immunity to get the better and accurate result in digital format.
