Project Motivation• According to World Health Organization approximately
10 million people in a year die resulting from cardiovascular complications
• In America every 20 second a heart attack occurs
• 50% die an hour from a heart attack due to not receiving
prompt medical attention
• Every minute a heart attack death occurs in America

Data Acquisition
• Originally an ECG heart monitor was purchased – Unfortunately the product was defective!
• We built an ECG circuit ourselves

Data Processing
• MC will continuously check for one type of abnormality
• Duration of Q wave reaching the baseline is the main criteria to detect heart attack

Normal Signal Heart Attack Signal
>180ms
11
Data Transmission
• As soon as heart attack is detected:– The Bluetooth Module will initiate a connection to
user’s cell phone
– One line of code is transferred to the cell phone to initiate the phone call to emergency personnel

Test Plan
• In order to test the heart attack signal, we used LabView to generate the signals.
• Signals are fed to MC, from the phone jack of the computer

Test Plan
• A circuit was built to invert the signal before feeding it to MC
• Moreover, DC offset was eliminated by using the circuit
