Heart attack is one of major cardiac disease. An electrocardiogram (ECG) is widely used to diagnose these diseases. Now a days, ECG monitoring is one of the major technique used in medical science. This is achieved by extracting amplitudes and durations of the parameter of ECG waveform such as P wave, QRS complex, RR interval and PR durations, temperature and heart beat. These parameters are compared with the normal values to determine the type of abnormalities. Under critical conditions, transmission scheme will ensure successful transmission of critical messages to doctors via Global system for mobile (GSM) network.
