Q: Bradycardia refers to: 

A. Heart rate above 100 beats per minute
B. Heart rate under 60 beats per minute
C. Increased heart contraction force
D. Decreased heart contraction force

  • Bradycardia refers to a slower than normal heart rate (under 60 beats per minute)
  • Tachycardia refers to a faster than normal heart rate (over 100 beats per minute)

The normal heart rate for adults is 60-100 beats per minute. Also, remember that the heart rate for children and infants is faster.

  • Child: 80-120 beats per minute (bpm)
  • Infant: 100-160 beats per minute (bpm)

Tips for memorization: “B” in Bradycardia like “Bus,” and “T” in Tachycardia like “Train.” The train is faster than the bus (usually).


Answer: (B). Heart rate under 60 beats per minute


Let’s review a few more concepts in medical emergencies or medical conditions for the dental assistant exams. What sounds similar to bradycardia/tachycardia?

  • Bradypnea is a slow respiratory rate, below the normal rate
  • Tachypnea is a rapid respiratory rate, above the normal rate

Same concept with brady vs. tachy here. Since we already memorized the trick, we can understand those two concepts so much better! For everything you try to memorize for the dental assistant board exams or school exams, make yourself some tips. Use your senses: sound, touch, feeling, image, emotion, or anything that is more than just words.
