Does oxygen pulse trajectory during incremental exercise discriminate impaired oxygen delivery from poor muscle oxygen utilisation?

A flattened or decreasing O2 pulse trajectory during incremental CPET is commonly found in patents with low exercise stroke volume but not in those with severely impaired muscle O2 utilisation. This finding should prompt additional cardiovascular work-up. http://bit.ly/2HRE739.
