Fig. 1From: A comparison of standard and high dose adenosine protocols in routine vasodilator stress cardiovascular magnetic resonance: dosage affects hyperaemic myocardial blood flow in patients with severe left ventricular systolic impairmentResults in healthy control group (n = 19). a Increase in heart rate (HR) between adenosine doses, b stress myocardial blood flow (MBF) between adenosine doses. In healthy subjects, no significant differences in MBF were seen between doses of adenosine despite significantly higher HR with high dose adenosine and long dose adenosineBack to article page
