Frequency domain assessment of the coupling strength between ventricular repolarization duration and heart period during graded head-up tilt

We test the hypothesis that the degree of correlation between ventricular repolarization duration (VRD) and heart period (HP) carries information on cardiac autonomic regulation. The degree of correlation was assessed in the frequency domain using squared coherence function during an experimental pr...
