This BIOPAC Basic script shows an example of how to place a marker at the peak of the selection. This script is particularly useful for manually marking the QRS peak in an ECG signal when the data is noisy.
Often the peak of the QRS is visible to the human eye but may not be easily identifiable by the peak detector. This approach allows the user to select the area around the peak and then run the script to place a marker precisely at the R-peak.
After marking the peaks, the data will be more useable for simple heart rate calculations or more advanced Heart Rate Variability analysis.
