Explanation / Answer

90) The normal heart rate in humans is between 60 to 100 beats per minute. When the heart rate is less than 60 beats per minute, it is called as bradycardia and when it is more than 100 beats per minute, it is called as tachycardia. Atrial flutter and atrial fibrillation are abnormal heart rhythms in which heart rate ranges from 150-400 beats per minute and more than 400 beats per minute respectively.

Therefore, the correct answer for this question is option (c) 100-160 beats per minute
