If a chicken has a heart rate of 275 beats per minute, what does this indicate?

  1. Bradycardia

  2. Tachycardia

  3. Normal heart rate

  4. Arrhythmia

The correct answer is: Normal heart rate

A chicken's normal heart rate typically ranges from about 250 to 300 beats per minute, depending on factors such as age and activity level. Observing a heart rate of 275 beats per minute falls within this normal range, indicating that the chicken's heart is functioning appropriately for its physiological needs. Therefore, identifying this as a normal heart rate aligns with standard avian veterinary knowledge. The other conditions, such as bradycardia (slower than normal heart rate), tachycardia (faster than normal heart rate), and arrhythmia (irregular heartbeat), do not apply here since the heart rate in question is well within the expected parameters for chickens. Understanding these ranges is crucial for veterinary technicians as it helps in assessing avian health and responding to potential issues effectively.
