Abstract: Cardiac arrest is a sudden, abrupt stopping where the heart malfunctions and causes breathlessness, unconsciousness and often leads to a person's death. Today, 85% of the cardiac arrests happen outside the hospitals and it accounts for the 24.8% (2010) of the total deaths in India. Rural areas compared to urban areas are affected more due to the lack of proper hospitalization facilities and awareness of Cardiac Vascular Diseases (CVD). The causes of CVD maybe arrhythmia, cardiomyopathy, valvular heart diseases, sudden heart attacks or electrical malfunctions in the heart. It is said that resurrection by CPR or electric shock in a timely manner can save many lives. Here we propose to design a system to overcome this problem by integrating a pulse oxi-meter in a smart watch to a mobile application and a portable ECG system. The pulse-oximeter records our pulse variations and when the change in variations goes below the threshold value, a beep is sounded from the watch and alert is sent from the mobile application to registered emergency contacts. The user is asked to use the portable ECG and immediate report is sent to user application. If the report appears erratic or has a cause for concern, an alert for ambulance is sent if the patient is at home, or when outside they are urged to go to the hospital. This way, we can give timely intervention to prevent death.

Keywords – CVD, Sudden Heart Attacks, Pulse-oximeter, Wireless Portable ECG, Smart Watch, User Application.
