From: Ambulatory electrocardiographic longitudinal monitoring in a canine model for Duchenne muscular dystrophy identifies decreased very low frequency power as a hallmark of impaired heart rate variability

Figure 5

Heart rate variability—Time–frequency analysis. On all the graphs, the evolution of GRMD dogs’ values are represented by red dots, and healthy dogs’ values by blue dots. A line indicates the median of each population at each timepoint. Asterisks symbolize a significant difference between GRMD and healthy dogs at a given timepoint (post-hoc Fisher LSD test p < 0.05). (A) Very low frequency (VLF) power. (B) Low frequency (LF) power. (C) High frequency (HF) power. (D) Total power. (E) Low Frequency/High Frequency (LF/HF) ratio (F High frequency power, expressed in normalized units (HF n.u. = HF/(LF + HF)).
