What is tachycardia defined as?

Tachycardia is defined specifically as a rapid heart rate exceeding 100 beats per minute. This condition indicates that the heart is beating more quickly than what is considered normal, which can occur due to various reasons, including stress, fever, anemia, or underlying heart conditions. Recognizing tachycardia is essential in healthcare, as it can signal potential issues that may require medical attention.

Understanding the baseline heart rate ranges is crucial. A heart rate below 60 beats per minute is classified as bradycardia, while a normal resting heart rate typically falls between 60 to 100 beats per minute. An irregular heart rate pattern refers to arrhythmias, which are distinct from tachycardia, as they may involve erratic heartbeats, not necessarily a rapid rate. Thus, the definition of tachycardia specifically highlights the increased heart rate, making the distinction clear.
