Abstract:
This paper illustrates a wireless system developed for offline ECG transmission and its remote processing. At the transmit end, a standalone embedded system collects short duration ECG samples from the source, stores them in a RAM and then encodes these using a customized bi-phase modulation for offline transmission in ISM band. At the receive end, another embedded system extracts ECG data from the demodulated output of the wireless receiver and delivers to a desktop computer using the serial port. An application software stores these samples in a text file. At first, the bit error and packet error are computed from the received dataset. Then, computed ECG wave durations and intervals along with lead data plot are generated on a Graphical User Interface for preliminary level diagnosis. Test results with synthetic ECG from PTB diagnostic ECG database (ptb-db) for short range of communication are reported.

Electrocardiogram Fundamentals
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.
