Wearable ECG monitoring is becoming a convenient way for patients as well as doctors, in tracking and diagnosing heart diseases among large population in rural areas. Wear- able ECG devices along with the smartphones are used to capture and transmit ECG data to hospitals where medi- cal practitioners diagnose and make suitable interventions. ECG electrode cable misplacement poses signicant chal- lenge when untrained population is the end-user. We present a real-time lead misplacement detection system for Mason- Likar lead conguration to provide immediate feedback to patients. It reduces chances of pseudo-disease diagnosis as well as the need for technicians to conrm the validity and quality of captured ECG data. The eld test results show that six dierent Mason-Likar electrode misplacement can be detected and dierentiated from a normal one with a condence value p=0.05.
