1. Portable ECG Collection System Joe Konwinski James Cook Carmen Hayes Mentor: Dr. Mingui Sun February 1 st 2005

2. Outline Significance Introduction to our project My Focus Specific Aims Design of Miniature ECG amplifier Memory Mechanism What is feasible?

3. Significance The leading cause of death in the United States is heart disease. 2003 Statistics: 23.0 million+ were diagnosed 700,000 died

4. Significance (cont’d) 15.6% of US people have no health insurance Insurance isn’t getting any cheaper Exploiting Preventative Medicine Is Hot

5. Introduction Develop a small device that can: Cleanly amplify the electric activity of the heart Save the amplified signal onto flash memory Produce a program that can: Analyze the ECG data and give heart-risk feedback to the user Be Sold Over-the-Counter Be User Friendly and Safe

6. Intro (cont’d) Purpose is: To assess heart risk of seemingly HEALTHY, middle to upper aged individuals To give a cheaper/ less demanding alternative for healthy patients Purpose is NOT: To replace a health professional in assessing heart risk of ILL or HEAVY RISK individuals

7. My Focus Develop miniature ECG amplifier Research methods to store time-continous data Interface ECG amplifier with storage device

8. Specific Aim I Development of Miniature ECG Amplifier Deciding on Chips Bread-Board Model PCB development Testing PCB model

9. Specific Aim I (cont’d)

10. Deciding on chips Size Power Consumption Chip Quiescent currentSupply voltage INA332 450µA+2.7 - +5.5 V OPA2336 20µA+2.3 - +5.5V

11. Specific Aim I (cont’d) PCB development PCB express Copper-Clad Board Thin Two-sided

12. Specific Aim II

13. Specific Aim II (cont’d) Implementing Flash Memory Control TDK’s® GBDriver© Provides control over CompactFlash™,Smart Media™ Controls up to 2GBytes of Flash Memory

14. What is Feasible? Construction of functional, miniature ECG Filtering Techniques to bring electrodes as close as possible Computer program to detect peak-peak times in signals Flash memory storage????
