PC based ECG interpreter

Today no tool is available which can be used to analyze routine 12 lead ECG data. Computers with higher capabilities are available at reasonable cost. The capabilities of these computers allow one to use digital signal processing concepts at least for low frequency signals. The ECG signal has frequencies in the range 0 to 40 Hz. Only patients having heart diseases will have frequencies in their ECGs which will be above 50 Hz. At the most frequencies would be around 100 Hz. This is definitely a low frequency range and one can use todays PCs in this range. A tool has been evolved to analyze the routine 12 lead ECG data and to interpret it. Here the sampling frequency chosen to digitize ECG signal is 500 Hz with 12 bit resolution (prescribed standard). Each lead is digitized for a 3 second duration. This tool will be of great help as the doctors need not go through the ECG paper roll. The record and transport of data will be simplified. The developed tool is for certain classes of ECG only.
