Abstract - The Electrocardiogram (ECG) is the most
tissues of the body. Every heart beat is caused by electrical impulses from the heart muscle that causes the atria and then the ventricles to contract and consequently pump blood to the lungs and the rest of the body. This electrical activity of the heart is measured by the electrocardiogram which serves as a means to detect for irregular heart conditions and possibly heart diseases.
clinically used biological signal and it is the means of detecting several cardiac diseases and abnormalities. A condition of abnormal electrical activity in the heart which is a threat to humans is shown by this electrocardiogram. It is a representative signal containing information about the condition of the heart. The of the P-QRS-T wave shape and size and their time intervals between its various peaks these are all contain useful information about the nature of disease affecting the heart. This paper presents a technique to examine electrocardiogram (ECG) signal, take out the features for the heart beats classification. Collect data from database. The heart rate is used as the base signal from which certain parameters are extracted and presented to the classification. Heart rate assessment, as well as heart rate variability parameters are computed in real time directly on the sensor, thus only a few parameters are sent via wireless communication for power saving. Hardware and software methods for heart beat detection and variability calculation are described and preliminary tests for the evaluation of the sensor are presented.

1. INTRODUCTION Wearable systems for patients remote monitoring consist of three main building blocks: 1) the sensing and data collection hardware to collect physiological and movement data, 2) the communication hardware and software to relay data to a remote center, and 3) the data analysis techniques to extract clinically-relevant information from physiological and movement data. Recent advances in sensor technology, telecommunication, and data analysis techniques have enabled the development and deployment of wearable systems for patients' remote monitoring. Researchers have relied upon advances in the above-mentioned fields to address shortcomings of ambulatory technologies that had previously prevented long-term monitoring of patients' status in the home and community settings. The state of cardiac health is generally reacted in the shape of ECG waveform and heart rate. It may contain important pointers to the nature of diseases a6icting the heart. The heart is the most vital organ of the human body since it acts as a pump that pushes oxygen‐rich blood to the organs, cells, and

1.1 Objective To detect such abnormalities, a variety of methods have been used in the literature. Innovations in electronic healthcare are revolutionizing the involvement of both doctors and patients in the modern healthcare system by extending the capabilities of physiological monitoring devices. Despite significant progress within the monitoring device industry, the widespread integration of this technology into medical practice remains limited. The purpose of this paper is to summarize the developments and clinical utility of smart wearable device with body sensors.
