Step 1 :Given that the pulse rate is 116.4 beats per minute.
Step 2 :We are also given that significantly high values are 106.4 beats per minute or higher.
Step 3 :Comparing the given pulse rate with the limit for significantly high values, we find that 116.4 is greater than 106.4.
Step 4 :\(116.4 > 106.4\)
Step 5 :Therefore, the pulse rate of 116.4 beats per minute is significantly high.
Step 6 :\(\boxed{\text{The pulse rate of 116.4 beats per minute is significantly high.}}\)
