Tachycardia is defined as a heart rate greater than what value?

• A. 60-100 bpm
• B. >100 bpm
• C. <60 bpm
• D. 120-140 bpm

Answer: (B)

Tachycardia means a heart rate that is faster than normal at rest. For adults, a normal resting heart rate is about 60 to 100 beats per minute, so tachycardia is defined as a resting rate exceeding 100 beats per minute. This threshold helps distinguish a fast heart rate from normal physiological increases during activity or stress. Values within 60–100 bpm are considered normal, while rates well above that (such as 120–140 bpm) aren’t the standard cut-off for tachycardia, though they indicate a very fast rate. Keep in mind that heart rate can rise temporarily with exercise, fever, or anxiety, but persistent resting rates above 100 bpm define tachycardia.
