All data represents mean± standard error mean (SEM).
a)
Represents the statistical analysis method between pre and post.
b)
Means the statistical analysis method between Ylang-Ylang group and control group. aVR, aVL, aVF mean lead augmented vector right, lead augmented vector left and lead augmented vector foot, respectively.
