Which of the following best describes tachycardia?

Tachycardia is characterized by a heart rate that exceeds 100 beats per minute. This condition can occur in various situations, such as during exercise, due to stress, or as a response to certain medical conditions. Understanding tachycardia is essential, as a heart rate within this range may indicate an underlying health issue that could necessitate medical attention.

The other options describe different heart rate conditions: a rate of less than 60 beats per minute is referred to as bradycardia, whereas a steady heartbeat between 60 to 100 beats per minute is considered a normal heart rate. An irregular heartbeat pattern does not specifically indicate tachycardia, as tachycardia refers solely to the rate and not the rhythm of the heartbeat.
