Figure 1: HF Hearts Have Longer APDs, Which Are Shortened by RDN

(A) Representative apical action potentials in the apex of the hearts of sham control (CTL), heart failure (HF), and HF plus renal denervation (HF+RDN) hearts are shown. (B) Summary data of action potential duration for all the groups are shown. The HF hearts have a longer mean action potential duration (APD) than CTL hearts. The HF+RDN hearts have a shorter mean APD compared with the HF hearts. Data represent mean ± SD; *p < 0.05 HF versus CTL group. #p < 0.05 HF+RDN versus HF group.
