Q&A Portion
“I frequently have ECG/ICG waveforms where the Q and B points are not plausible when placed as perfectly as you had in the initial ICG slide. I often have to move the Q to the right, or b to the left. Why would this be?”: 53:24
“I’ve run into some trouble measuring the distance between the two front electrodes depending on what the participant is wearing, as well as their body type given variation in the size of people’s chests. Do you have advice on obtaining that measurement? What is the margin of error for that measurement/how accurate does that measurement need to be to obtain valid ICG data?”: 54:04
“Is B point calibration method set automatically for each dataset or does it need to be changed manually depending on whether the B point inflection is apparent or not?”: 55:28
