Figure 5From: Quantification of myocardial blood flow with cardiovascular magnetic resonance throughout the cardiac cycle Correlation between MCV and peak heart rate at stress. There was a strong linear negative correlation between the maximal cyclic variation (MCV) in stress MBF and the peak heart rate during adenosine-induced maximal hyperemia in healthy volunteers (n = 30). MBF = myocardial blood flow.Back to article page
