QEcg: Linux Electrocardiograph Reader

Jelani John

Most computer electrocardiogram programs require the use of a special Data Acquisition card. QEcg is a program to acquire an electrocardiogram through the sound card on a Linux computer. The program displays the ECG and calculates heart rate. This program can be used with an ECG simulator or even a real ECG (although the ECG will need to be amplified using a circuit such as that described here or here [local copy]). Just connect the ECG output to the sound-card and run the program. It only works under Linux.

This software was ported from the original Windows version described here. Or you can click here for a local copy.

Program requirements:
- Qt version 3.x or most recent version.
- A recent version of the gcc compiler.
- 8 bit minimum sound-card.
- Linux.
