This document describes the development of a personal wireless ECG system with remote monitoring capabilities by a senior capstone design team. The system aims to address delays in treatment for heart attacks by allowing real-time ECG monitoring and transmission to medical professionals. The team created a non-invasive device that transmits ECG signals via Bluetooth to an Android smartphone for display, and then sends the data over 3G networks to a secure website for remote viewing. Both major objectives of developing the smartphone interface and enabling remote monitoring were completed.

1. Development of a Personal Wireless ECG
System with Remote Monitoring Capability
Senior Capstone Design, Spring
2011
Identification of Problem:
Nearly 6 million Americans are
afflicted with heart failure every year,
and this is a quickly rising trend.
(American Heart Association,
2006)
Current average time from episode-
intervention can be fatally long (1 to 4
hours)
1.Recognize attack
2.Notify help
3.Locate patient
4.Transport to hospital
5.Intervention Preparation
6.Treatment
Heart tissue begins to die within
minutes, and after about an hour this
damage can become permanent.
