The ECG interpretation is majorly driven by event detection, i.e. QRS onset and end, QT time, P wave etc. From these we can determine the normal heart rhythm, and some performance measures, like heart rate etc. The ECG waveforms, however, are much less understood. This is a pity, as ECG waveforms, provide instantaneous information on the electrophysiological and structural function of the heart. In this respect it is interesting to know if there is something like a normal ECG waveform or normal PathECG (CineECG). This latter technique is a vector-based method to estimate the electrical position of a moving vector within the heart. Similar normal distributions can be created to compare to the normal ECGs.
Topics Discussed:
How can we define a normal ECG waveform?
What is needed for an accurate waveform comparison?
Are normal ECGs waveforms different from abnormal ECG waveforms?
Did you use this method to classify ECGs as normal or abnormal?
