| The Electrocardiograph (ECG) measures electrical changes of tissue surrounding the heart to create a time based representation of the operation of the heart. Ambulatory ECGs (AECG) are used extensively in medicine to detect and diagnose intermittent heart conditions. The purpose of this research is to study AECG telemetry systems, from design to implementation. To meet this goal a real-time AECG telemetry system was developed. It is inexpensive, wearable, can operate for forty-eight hours, is capable of measuring 1-lead of ECG data, and uses Bluetooth(TM) communication. It has the capability to detect heart rate and rhythm. Software running on a receiving computer displays, stores and analyzes the incoming ECG data. This system forms the basis for a wireless network of miniature body-sensors capable of measuring various biological signals. Future goals include more robust analysis and noise suppression methods, and increasing connectivity to the internet and cellular telephones, using the Bluetooth(TM) connection. |
