What is the term for a fast heart rate exceeding 100 beats per minute?

Tachycardia is the medical term used to describe a fast heart rate, which is defined as exceeding 100 beats per minute. This condition can occur for various reasons, including physical exertion, stress, fever, or underlying health issues such as heart disease. Understanding tachycardia is essential for healthcare professionals, as it can be a sign of an underlying problem that may require assessment and intervention.

In contrast, bradycardia refers to a slower-than-normal heart rate, typically below 60 beats per minute. Arrhythmia refers to any irregularity in the heart's rhythm, which can include both fast and slow heart rates, making it a more general term. Bradyarrhythmia combines elements of both bradycardia and arrhythmia, indicating a slow and irregular heart rate. Therefore, tachycardia is the specific term that best fits the description of a heart rate exceeding 100 beats per minute.
