Abstract:
After a heart attack, the first few hours are critical in saving much of the dying heart muscle which are starving due to lack of oxygen supply and preventing permanent heart damage. The symptoms vary from individual to individual and the most common reason for critical delays is medical treatment is patient unawareness and lack of early warning. It is possible to detect the onset of a heart attack and inform the doctor or person concerned. By implanting a chip into the body, the patient need not worry about device operation. The patient will only be required to carry a cell phone equipped with Bluetooth and GPS. As soon as the implanted chip detects a heart attack, it will alert the cell phone which in turn will automatically call for help and provide the patient’s location. Thus it helps in providing early heart attack detection so that the patient can get medical attention within the first few critical hours. It consists of three basic sub projects ECG Circuit, Analysis Algorithm, GPS module, GSM module and microcontroller. The first unit is worn on the user’s wrist captures abnormal heart beat signal from the patient , and the rest units are installed in the stick. The microcontroller on the stick runs a heart attack algorithm. Warning is given out to the person about his heart condition. The emergency calling system calls for medical help at the moment of heart attack. The effectiveness of the proposed method is confirmed by experiments on a commercially available walking stick. Each of the subprojects responded positively. The proposed Walking Stick with Heart Attack Detection is cost effective and can save the lives of millions of old people by helping them in getting the earliest medical help in the condition of heart attack. Here we use GPS device and GSM module so at a worst conditions it will directly call 108 emergency and patient’s life will be saved.
