The Biopac Student Lab system can be used to amplify and enhance the ECG signal using a clinical diagnosis tool referred to as the Signal Averaged ECG. The technique allows identification of small electrical currents, called ventricular (ven-TRIK’u-ler) late potentials. This test is used to help identify people at risk of a dangerous rhythm in the heart’s lower (pumping) chambers. This is called ventricular arrhythmia (ah-RITH’me-ah) and it can lead to sudden cardiac death.
For years, cardiologists examined paper charts of ECG signals to create an averaged ECG complex. They took each individual cardiac cycle, measured each part of the complex with a ruler, wrote down each value, and calculated the means to derive an averaged ECG complex. This task took a great deal of time and patience. When the need arose to analyze two or more different scenarios (e.g., baselineresponse), the task had to be performed even more carefully for accurate comparison of the ECGs.
The BSL PRO software has a powerful averaging feature that automatically derives an averaged signal from a specific number of cycles (averaging is found in the Find Peak dialogue). It also can easily compare two, three, or more averaged ECG signals.
