Roughly 1980, Tom.  And no, it was an absolute drop in CO due to the 
inability of the heart to refill completely between strokes.  The SV starts 
to drop pretty severely as the HR climbs past a certain point, and when you 
get to the point of fibrillation the SV drops to zero so the CO does, too.  
Since I read the actual paper in English, I'd stick to English-speaking 
countries of origin.  And since the data was collected from multiple species, 
I have a feeling it was in a cardiology publication rather than one that 
stuck primarily to equine research, but maybe not.
