Refer to http://en.wikipedia.org/wiki/Electrocardiography for an understanding of ECG signal and leads. Conventionally such ECG signals are acquired by ECG acquisition devices and those devices generate a printout of the lead outputs. A cardiologist analyzes the data for checking the abnormality or normalcy of the signal. But in recent times, automatic ECG processing has been of tremendous focus. http://www.codeproject.com/KB/cpp/ecg_dsp.aspx gives a fantastic overview of acquiring and filtering ECG signals through inexpensive hardware into your PC. You can download ECG signal samples of various diseases from http://www.physionet.org/physiobank/database/mitdb/. Now the main point of concern is how to develop a system for extracting the features from ECG signal so that these features can be used for Automatic Diseases Diagnosis. In this Article we shall discuss a technique for extracting features from ECG signal and further analyze for ST-Segment for elevation and depression which are s
