Cardiograph sound3/16/2023 The conclusion of this study: The result of the design of microcontroller ATMega program listings can be used transform and run the program to the ECG machine to know the number of heartbeats, a beep sound every wave R the ECG signal, displayed on the graphical LCD, PC, printed through a computer, and can be stored in computer. An echocardiogram may use several special types of. While the design ECG machine through the stages as follows: circuit design, circuit testing and calibration output. These sound waves are sent to a computer that can create moving images of the heart walls and valves. The independent variable ECG phantom or human and the dependent variable is the ECG machine. To answer the research objectives, the design of the research is to use pure experimental research is the design of experimental series. The Philips PageWriter TC50 cardiograph is an advanced, reliable, and compact ECG solution, that is easy to use. Objective is to design a ECG machine using ATMega microcontroller technology, by making a series of bio amplifier ECG, measuring the amplitude and frequency response bio amplifier, and make the ECG signal processing circuit with microcontroller, which can be displayed on a 128圆4 graphic LCD or PC. As this sound energy passes through tissue, it is reflected at interfaces of differing acoustic impedance to the same transducer, which also acts as a receiver. In this study, the researchers designed ECG machine 12 channels to take advantage ATMega microcontroller technology, Graphic LCD 64x12, which can be obtained on the market at low prices, thus yielding a portable ECG apparatus, can interconnect with other devices and cheap. In efficient and display ECG still not interconnect with other devices. The red bars represent left-side events, and the black bars represent right-side events. An echocardiogram (echo) is a simple test which uses sound waves (ultrasound) to take a moving picture of your heart. ECG machine on the market, has a considerable cost, the technology used is still very complicated. Heart sound events represented graphically. An ECG may also be performed as a screening test in geriatric cats or cats that are undergoing anesthesia.
