Senior Project – Electrical Engineering- 2012
Heart Monitor Applicationfor Android
Craig SantangeloAdvisor – Prof. Hedrick
General Block DiagramProject 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.

Components
Heart Attack Algorithm1. Establish a baseline (average of all
samples in the PQRST waveform)2. Detect QRS peak3. Make sure the signal returns to the
baseline directly after the peak within approximately 100 ms (width of ST segment)
4. If signal does not return to the baseline within 100 ms of QRS complex, alert the victim and dial 911
