What is classified as tachycardia?

Tachycardia refers to an elevated heart rate, specifically when the resting heart rate exceeds 100 beats per minute (bpm). This condition can arise due to various factors, including stress, exercise, or underlying health issues. Understanding the thresholds for heart rates is vital in recognizing abnormalities. While resting heart rates less than 60 bpm are classified as bradycardia and rates between 60-100 bpm are considered normal or healthy rates for adults, a heart rate greater than 100 bpm signifies that the heart is beating faster than the typical resting range, aligning with the definition of tachycardia. Thus, the classification of tachycardia is accurately represented by a heart rate greater than 100 bpm.
