Prototype ECG Monitoring System
According to Bruce Stanko , A patient’s heart rate is measured and recorded using an ECG monitoring equipment. A computer is used to store the information gathered from this monitor. This ECG monitor is intended so that a doctor may monitor a patient without needing to be in the same room as the patient at all. The project’s goal is to address typical ECG data collection issues. Remote transmission of ECG signals from patient to practitioner is also a goal.
In addition to the features of a centrally-based ECG machine, a portable wireless ECG monitoring system may also interface with other devices through wireless connections. It is digitally processed and transported the micromodules that are connected to the electrodes. The ZigBee module transfer techniques were employed in the project. After building the monitoring system, it may be moved to a new location. The project was finished successfully and has been presented as a viable healthcare alternative.
Bruce Stanko Explains ,A portable ECG terminal and a health monitoring center are the project’s main components. The Zigbee communication module used by the health monitoring center communicates with the portable ECG. To monitor the patient’s status and give therapy based on the ECG’s signals, doctors utilize the ECG’s signals. A PIC16F877 microcontroller with low power consumption is used in this project. The following images demonstrate the pinout.
An ATmega328P microcontroller is used to build the DPU. As a result, it is capable of displaying a typical ECG signal in its entirety. Like the design of MATLAB’s GUI, the outcome of this endeavor is comparable. LabVIEW’s GUI design is interoperable with MATLAB and LabVIEW, as well as other operating systems. User diagnostics may also be performed via the system’s software interface.
A one-cycle ECG signal will be shown throughout the design process. T, P, and QRS waves will be seen in this ECG signal. The time it takes for the electric impulse to go from the atria to the ventricles is best measured by the T wave. High R waves and a modest S waves make up the QRS complex wave. It follows the T wave, which is followed by a P wave, and then by another T wave.
Bruce Stanko Revealed , The microcontroller will serve as the detection and measurement processor throughout the design phase. The ECG and heart rate will be handled entirely by the MSP430. A low-pass filter will be used to remove high-frequency noise from the signal. Heart rate and the QRS wave may be detected by using an MSP430. ZigBee networks or personal computers will receive the data.
The gadget will apply initial amplification to the ECG signal once it has been processed. There must be a CMRR of at least 120 dB in order to avoid signal deterioration. An ECG should have a gain of at least 13 mV. It ought to be simple to use, and it should be. With just a few mouse clicks, a clear ECG signal may be obtained. The equipment should additionally record the patient’s pulse in addition to monitoring the patient’s heart rate.
In order to eliminate interference from the 50Hz power line, the ECG signal will undergo notch filtering. The result will be an ECG signal that is clear. The DAU is built on this basis. As a medical device, it is also utilized. A low-cost heart rate monitor is provided by a decent ECG monitor. This will make it easier to keep an eye on things. It is possible to construct a low-cost ECG monitor for about $20.
Low-pass filtering of the ECG signal follows the active high-pass filter. Using a low-pass filter reduces high-frequency noise from the signal. The ECG signal is more accurate when it is passed via a low-pass filter. The electrode frequency offsets will be eliminated, and the low-frequency noise will be reduced. An active high-pass (low-pass) filter will be used in the ADU’s second stage.
