There are many situations where the patient needs regular or daily observation but this is difficult to do as it mingles with the lifestyle of the patient. To solve this problem a system can be developed which is easy to carry and which checks the health parameters like temperature, heart rhythm, heartbeat and blood pressure of the patients continuously. This smart ECG can be worn by inpatients or outpatients and monitored in real-time. Healthcare professionals can access patients' data wirelessly in real time with their smartphones. This system can be useful especially for senior citizens who live alone or have a disability. Therefore, this proposed system can be utilized for remote medical systems to assist the elderly patients, for self-testing diagnostics, or for physicians to diagnose diseases of the circulatory system. The proposed system consists of electrocardiogram (ECG) which assesses the heart rhythm, diagnose abnormalities of heart and pulse oximeter which calculate the vital parameters of the patient and store this information using Arduino Mega. This system would be very helpful as the patient's health condition is regularly checked without the patient going to the hospital for regular checkups and this will also help the patient financially. In case of dire conditions like heart stroke and problems with blood pressure, the location of the patient is found using GPS and the patient can be treated immediately. The system is then connected to the smartphone through Bluetooth and the patient's health parameter information is displayed in an app. These kinds of systems are very promising in these cases due to the decrease in prices, increase in data storage capacity, availability of various sensors and standard communication interfaces, best user interface using a touchscreen.
