Daytime increase in the three temporal dispersion indexes (QTeVI, QTpVI and TeVI) related to the circadian variation in SGNA/VNA seven weeks after MI (right panel). Note that the SGNA/VNA peak (m= 2.7; amp= 0.4; ac: 10:00; th: 1:00; p= 0.0001) matched the QTpVI (m= −1.46; amp= 0.39; ac: 9:00; th: 2:00; p= 0.0001) and TeVI peak (m= −1.18; amp= 0.37; ac: 12:00; th: 2:00; p= 0.005). In the evening there was the QTeVI peak (m= −1.29; amp= 0.18; ac: 18:00; th: 2:00; p= 0.0043) corresponding to an evening SGNA/VNA peak.
