We do PT and AT waveforms along with the pressure measurements, noting that
the signals are "sharp and multiphasic."
I believe 93924 deals with treadmill exercise. We use toe-raises (see
archives for a scuffle about the relative merits), which fall under 93923
along with reactive hyperemia. This pretty nearly exhausts my knowledge of
