Figure 2 Polar map of ¹²³I-MIBG images and three-dimensional diagram of wavelet analysis of RR interval variability in two representative patients with mild myocardial ischemia provoked during BCO. These patients had a fall in LVEF (<10%) by BCO. The LF components were augmented in the patient without cardiac denervation (left), whereas no change in the spectral components was found in the patient with cardiac denervation (right). Abbreviations as in Figure 1.
