Correction to: Journal of Nuclear Cardiology® Volume 21, Number 6;1223–9 10.1007/s12350-014-9952-y
Regrettably the original version of the above article contained errors in Table 2 and wrong values in the text. The corrected table is presented here and the values which have been corrected now appear in bold text.
Page 1223 Abstract
Global MBF showed an increase from 180.2 ± 59.9 to 193.6 ± 60.8 mL minute/100 g (P = .002) after beta blocker withdrawal.
Page 1225
Mean systolic and mean diastolic blood pressure during adenosine were nearly identical (P = .77 and P = .79) with and without beta blocker. Mean heart rate and mean RPP during adenosine significantly increased after beta blocker withdrawal by 15.2% ± 17% (P = 001) and 16.2% ± 23% (P = .004), respectively.

The data are listed in Table 2, lower third. Global MBF showed a significant increase by 7.4% ± 10% (P = .002) after beta blocker withdrawal. The individual data are depicted in Figure 1. All but three patients had a lower global MBF without beta blocker than with. The segmental MBF values (Figure 2) demonstrated a strong correlation over the entire range of perfusion values. The average effect was a slight perfusion shift of about 1015 mL minute-1/100 g in the range of 100-300 mL minute-1/100 g. The mCR under adenosine declined by 8.1% ± 11% (P = .038) and the normalized RPP by 16.2% ± 21% (P = .004) after betablocker discontinuation
