ECG editing in extrasystoles and rhythm abnormalities - II

This is a 38-years old doctor who had atypical chest pain and came for a cardiac CT. Though his rhythm was stable (Fig. 1), there was an abnormal band seen on the VRT image (Fig. 2). This was because of an abnormal down-slope on the 9th heart-beat after the T wave, as against an up-slope at all other heart-beats. A simple disabling of this offending beat (Fig. 3), improved the image quality dramatically (Fig. 4), though not to an absolute perfect level.
