The dates on the papers were 1970, 1988, 1990 and 1991.  I can send you
the complete references if you want them.  The 1988 and 1990 studies
were done by Evans (not me) and Rose, and I know their lab is very
well-equipped with ECGs, so I would certainly assume so.  The 1970
paper, no clue.  The 1970 paper was the one that reported HRs in
Standardbreds of 210-238 bpms, with an average max HR of 221 bpm.
