Health monitoring and technologies related to health monitoring is an appealing area of research. The electrocardiogram (ECG) has constantly been the mainstream estimation plan to evaluate and analyse cardiovascular diseases. Heart health is important for everyone. Heart needs to be monitored regularly and early warning can prevent the permanent heart damage. Also, heart diseases are the leading cause of deaths worldwide. Hence, this work presents a design of a mini wearable ECG system and is interfacing with the Android application. This framework is created to show and analyse the ECG signal obtained from the ECG wearable system. The ECG signals will be shipped off an Android application via Bluetooth device and Wi-Fi. This system will automatically alert the user through notification. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
