From: Physiologic heart rate dependency of the PQ interval and its sex differences
The results of the heart rate bin analysis (see the text for details) of PQ intervals (top panel), P wave durations (middle panel) and QT intervals (bottom panel). The analysis was performed for heart rate bins centred at heart rates between 60 to 100 beats per minute (with bin widths of ±5 beats per minute). The full red and blue lines show the averages of interval measurements per heart rate bins in females and males, respectively. The dark red and blue areas are the 99% confidence bands of the sex-specific averages (the dark violet areas show the overlaps between the confidence bands of both sexes); the light red and light blue areas are the ±standard deviation bands of the sex-specific averages (the light violet areas show the overlaps between standard deviation bands of both sexes).
