1. Senior Project – Electrical Engineering- 2012Heart Monitor Application for AndroidCraig SantangeloAdvisor – Prof. Hedrick Project Goal: To reduce the amount of deaths caused by heart attacks by combining the use of a cell phone with a hospital monitoring system. This system will monitor the heart’s electrocardiogram waveform, detect a heart problem if one arises, and automatically call for help. General Block Diagram SYSTEM Kendall Q-Trace 5400 Resting ECG Electrodes Heart Attack Algorithm Establish a baseline (average of all samples in the PQRST waveform) Detect QRS peak Make sure the signal returns to the baseline directly after the peak within approximately 100 ms (width of ST segment) If signal does not return to the baseline within 100 ms of QRS complex, alert the victim and dial 911 http://storkmedical.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=DL_ECL5400 http://www.pepidonline.com/emrdemo2003/emr/diagnosis/diagnosis_pic.asp http://www.vernier.com/experiments/hp-a/12/analyzing_the_heart_with_ekg/ http://www.cvphysiology.com/Arrhythmias/A013a.htm Analog Circuit ECG Waveform Components • Instrumentation • Amplifier • Input Driver • Optocoupler • Output Driver • High Pass Filter • Low Pass Filter • Output gain stage
