Tachycardia is defined as a resting heart rate of at least how many BPM?

• A. 90 BPM or Higher
• B. 100 BPM or Higher
• C. 110 BPM or Higher
• D. 120 BPM or Higher

Answer: (B)

At rest, a normal adult heart rate typically ranges from about 60 to 100 beats per minute. Tachycardia means the heart is beating faster than normal while at rest, defined conventionally as a resting heart rate of 100 beats per minute or higher. So 100 BPM is the lower bound for this condition, making it the best choice. Values like 90 BPM are within normal at rest, while 110 or 120 BPM are tachycardic examples, but the threshold used to define tachycardia is 100 BPM or more.
