Wireless body area sensor networks low-powerintegrated circuits, and wireless communications have enabledthe design of low-cost, miniature, lightweight, and intelligentphysiological sensor nodes. These nodes, capable of sensing,processing, and communicating one or more vital signs, can beseamlessly integrated into wireless personal or body networks(WPANs or WBANs) for health monitoring. These networkspromise to revolutionize health care by allowing inexpensive,non-invasive, continuous, ambulatory health monitoring withalmost realtime updates of medical records via the Internet.This paper proposes a power and area efficientelectrocardiogram (ECG) acquisition and signal processingapplication sensor node for wireless body area networks (WBAN).This sensor node can accurately record and detect the QRS peaksof ECG waveform with high-frequency noise suppression. analogfront end integrated circuit (IC) and digital application. ThisECG sensor node is convenient for long-term monitoring ofcardiovascular condition of patients, and is very suitable for onbodyWBAN applications.we minimize the other signal such as the ECG signal alongwith a bunch of noise is in analog form. In we use the High PassFilter (HPF) to filter the noise from the ECG Signals. The ECGis a voltage difference, recorded between two metal plates orelectrodes on the surface of the body
