1. Heart Savers Project Proposal Chris Hoffman Ryan Kellogg Mike Zizza January 31, 2007

2. Project Overview Now Now –Doctor's office or hospital -short visit –Holter monitor - continuous home monitoring  Asymptomatic – Don’t know when having a problem Later Later –Wearable ECG monitor that fits into daily life  Using 3 electrodes instead of 12 –Detect arrhythmia (irregular, faster, or slower) –Patients of all types

3. Competitive Analysis Heart Rate Monitor Omron Heart Rate Monitor Omron –Workout (optimal heart rate) –Chest strap with wrist watch Bio-Shirt Bio-Shirt –Marathon runners (performance) –Heart rate, temp, speed CardioNet CardioNet –24 hour wireless sensor –Doctor retrieves data over Internet

4. Requirements Functional Functional –Measure ECG and store relative data –Detect dangerous heart conditions –Display relevant information on phone Non-functional Non-functional –Low latency < few seconds  Measure data -> detect problem -> prompt –Low Power Consumption  Batteries last for approximately 6-8 hours –Portability  Worn comfortably and not interfere with activity

5. Specification Hardware Hardware –Nikotabs – Electrodes –ECG Signal amplifier –Robostix - I/O expansion board –Gumstix - Basix 400xm-bt –Smart phone (Nokia) Software Software –Java user interface (Phone) –Bluetooth stack protocol
