Disease of the heart is one of the death main cause in the world. Special attention to prevent more deaths from the heart disease is needed; one of them is early diagnose for heart disease with electrocardiogram (ECG). ECG represent electrical activity of the heart. The heart’s electrical activity can be recorded using some electrodes that is placed on certain body’s surface. ECG records can be used to determine abnormalities of the heart. We design a ECG monitoring system based on android smartphone and microcontroller unit. The ECG signal is obtained directly from patient using AD8232 module. Then, ECG signal is processed in microcontroller unit. Furthermore, the ECG signal is sent to Android smartphone and displayed in this device. We analyse the abnormalities of the heart using the heart rate from ECG signal. Heart rate is obtained from RR-interval in the ECG which represent the time interval between two detected R peak. We use modified Pan-Tompkins algorithm to detect the peak of R wave. The device that we design give good performance to detect and analyse abnormalities of the heart using heart rate. © Published under licence by IOP Publishing Ltd.
