What heart rate is classified as tachycardia?

• A. Below 60 bpm
• B. Between 60-100 bpm
• C. Above 100 bpm
• D. None of the above

Answer: (C)

Tachycardia is defined as a heart rate that exceeds the normal resting rate, typically recognized as being greater than 100 beats per minute (bpm). This classification is crucial in medical settings as it can indicate underlying health issues, such as stress, anxiety, fever, anemia, or heart-related conditions.

Understanding the normal ranges helps in identifying abnormal conditions: a resting heart rate below 60 bpm is classified as bradycardia, while a heart rate between 60 and 100 bpm is generally considered normal or benign in adults. It is vital for healthcare professionals to recognize tachycardia to assess potential medical interventions effectively. Thus, having a heart rate above 100 bpm is the hallmark of tachycardia, making it the correct classification in this context.
