When we conserve energy resources from any systems, our environment can enjoy cleaner air and a healthier, and we can help protect the climate by reducing heating due to more energy consumption. Energy Efficient medical equipment design is the latest research in medical science. Now, scientists are focus and shifting toward energy efficient medical system design. ECG machine is the most commonly used in medical equipments. If any equipment consuming less power than the environment, climate and whole medical regions will be move to greener, pollution-less and energy efficient. Finally, it reduces the cost of medical treatment and save energy consumptions. In this work, we are going to design and implement energy efficient ECG machine using LVDCI (Low Voltage Digitally Control Impedance), SSTL (Stub Series Terminated Logic) and HSTL (High Speed Transistor Logic) I/O standard.
