Abstract: One of the best ways to obtain health information is from an electrocardiogram (ECG). Through an ECG, characteristics such as patientsí heartbeats, heart conditions, and heart disease can be analyzed. Unfortunately, most available healthcare devices do not provide clinical data such as information regarding patientsí heart activities. Many researchers have tried to solve this problem by inventing wearable heart monitoring systems with a chest strap or wrist band, but their performances were not feasible for practical applications. Thus, the aim of this study is to build a new system to monitor heart activity through ECG signals. The proposed system consists of an embedded hardware in an armband. It is considered to be a reliable, robust, and low-power-transmission ECG monitoring system. The reliability of this system was achieved by the careful placement of sensors in the arm band. IoT is used as the protocol for data transmission.
