What does tachycardia mean?

Explanation:
Tachycardia means a heart rate faster than normal. For most adults at rest, a normal rate is about 60 to 100 beats per minute; when it rises above 100 bpm at rest, that’s tachycardia. It can occur for many reasons, such as exercise, fever, anxiety, dehydration, or certain medical conditions affecting the heart or its electrical system. Remember, tachycardia is a description of speed (rate) rather than rhythm—an irregular rhythm would be called an arrhythmia. So “faster than normal” best captures what tachycardia means.
