Time-Dependent Regional Myocardial Strains in Patients with Heart Failure with a Preserved Ejection Fraction

Figure 6

(a)–(f) Average rotation over one cardiac cycle for control (black) versus HFpEF patients (red). Rotation at each of the regions of the heart both endocardium (endo) and epicardium (epi) is displayed: base endo, epi (a, b), mid endo, epi (c, d), and apex endo, epi (e, f).
