Over the interval from 0 to 40 minutes, the line graph moves upward and to the right from 65 beats per minute at 0 minute, until reaching 80 beats at 9 minutes. It then moves horizontally, staying at 80 beats per minute until 32 minutes. The graph then moves downward and to the right, ending at 75 beats per minute at 40 minutes.

Over the interval from 40 to 74 minutes, the line graph moves upward and to the right from 95 beats per minute at 40 minutes, until reaching 120 beats per minute at 50 minutes. It then moves downward and to the right, until reaching 95 beats per minute at 62 minutes. The graph then moves upward and to the right, until reaching 120 beats per minute at 66 minutes. The graph then moves horizontally, ending at 120 beats at 74 minutes.

Over the interval from 74 to 100 minutes, the line graph moves upward and to the right from 140 beats per minute at 74 minutes, until reaching 160 beats per minute at 85 minutes.
