This aging of population causing many painful diseases because of unhealthy lifestyle. Heart diseases are on the top in that list. Electrocardiogram (ECG) shows the working of heart. To monitor heart condition as well as heart rate from the remote location will be preferable for both patient and doctor. Here we propose a real time multi-patient heart rate and ECG monitoring system using wireless sensor network which can be applicable for hospitals having many number of patients to be monitored as well as the patients who can be monitored from home also. This prototype proposes ECG and heart rate monitoring system at low cost. Key Words: Multi-Patient, Wireless Sensor Network, Cardiac Monitoring, Zig bee. 1. INTRODUCTION Population aging is the big problem in today’s era. Population aging means shift in the distribution of a country's population towards older ages.Aging of population causes expenses on medical issues. Today’s lifestyle is also a big reason behind it. Weight gain, poor diet, unhealthy junk and low nutritious food is not at all good for health. Busy lifestyle can impact your physical as well as mental health. These things last into depression and stress. All these things directly affects your heart as well as these things increase your medical expenses. Cardiovascular (or heart) diseases can be detected with cardiac monitoring. Cardiac monitoring can be of two types-1) External Cardiac Monitoring 2) Implementable and insertable cardiac monitoring. External cardiac monitoring is a traditional type of monitoring where the electrodes are located on pati ent’s body for between 24 hrs to 30 days. Devices monitor as well as store data. These monitoring devices can be connected to mobile devices. So experts can review that and can conclude about disease. Insertable and implementable cardiac monitoring is related with the electrodes are placed just under the skin. Patient can continue with regular activities once the wound has healed. This type of monitoring is required when patient needs long term of monitoring up to three years. Cardiac monitoring includes heart rhythm disorders also called cardiac arrhythmias. Heart beat is the result of electrical activities in heart while pumping of the blood. If there is malfunction in hearts activity then heart beats can be irregular, too slow or too fast. Sometimes irregular heart rate is not so serious, it may happen due to simple changes in lifestyle. But sometimes if patient feels recurrent fainting or unexplained strokes or artrial fibrillation- arrhythmias can be dangerous as well as potentially life threatening. In such cases continuous monitoring of heart activity is required because the predictions based on short term monitoring may fails. Cardiac monitoring at hospital is not possible in each case of patient because of cost as well as it is not possible for doctors also to allow large numbers of patients in the hospital for long time just for the observation purpose. On the other hand cardiovascular disease is responsible for an estimated 16.7 million deaths worldwide (30% of all deaths)[1].Another important aspect is of expenses on the solution of this problem should be less. Many devices and solution for heart monitoring have been proposed in the market.[2-5]They typically consist of monitoring, data logging and visualization of ECG with web or Smartphone with wireless devices. ECG signal filtration and processing requires a complicated as well as bulky circuit. As well as it requires more power to send data wirelessly. Due to bulkiness circuit cannot be portable or handy. With all these cost is the key issue. These devices should be at low cost. For all these reasons here we propose a real time multi patient heart rate and ECG monitoring system which is dedicated for the indoor environment of hospital as well as cardiologist can monitor patients if they are at home without any assistance. So the non-technical user can also handle it. This system has following benefits over existing systems as follows- 1.1Reduction in electrodes Typical ECG acquisition system is having minimum twelve electrodes attached on body. It is irritating to wear all these electrodes on body for long time. The system we propose, is having monitoring or analysis based on three electrodes. So it will be comfortable for user to wear it for
