Heart Attack Warning System Using Ecg Processing
Heart attacks are the most deadly CVD, Officially known as myocardial infarctions (MIs). Some people suffer sudden cardiac death, an event generally defined as death resulting from coronary heart disease (CHD), which usually leads to heart attack, within an hour of the onset of symptoms. Heart attacks occur when the supply of blood to the heart is interrupted, commonly due to the blockage of a coronary artery, which causes heart cells to die. When left untreated, the blockage of blood supply (ischemia) results in the infarction of heart muscle tissue (myocardium). Classic heart attack warning signs include chest/shoulder pain, shortness of breath, nausea, vomiting, and sweating. However, heart attacks frequently occur without any warning signs; these heart attacks are referred to as silent. "Over 50 percent of the patients suffering from a heart attack die just because they are unable to reach the hospital in time. It is highly imperative to detect early signs of heart attack & help the patient to reach hospital earliest possible. Real time monitoring of Electrocardiogram (ECG) would help in early detection of heart disease. Electrocardiography (ECG) is a widely accepted approach for monitoring of cardiac activity and clinical diagnosis of heart diseases. The proposed system implements a heart attack detection and warning system by real-time ECG monitoring. To obtain the patient’s ECG, a wearable sensor is used. The ECG will be classified as either normal or elevated. The signals are continuously transmitted to healthcare centre where the database of the patient is already recorded. If elevated beats occur for duration of at least thirty seconds (clinically significant) a multilevel system of warnings will begin. The user will immediately be notified via pop-up and audible alerts. Simultaneously a designated physician, ambulance and immediate family member of the patient will be notified via text message that the patient could be experiencing a heart attack.
