Definition
The upper threshold of a normal human heart rate is based upon age. Tachycardia for different age groups is as listed below:
- 1–2 days: >159 beats per minute (bpm)
- 3–6 days: >166 - bpm
- 1–3 weeks: >182 - bpm
- 1–2 months: >179 - bpm
- 3–5 months: >186 - bpm
- 6–11 months: >169 - bpm
- 1–2 years: >151 - bpm
- 3–4 years: >137 - bpm
- 5–7 years: >133 - bpm
- 8–11 years: >130 - bpm
- 12–15 years: >119 - bpm
- >15 years – adult: >100 - bpm
When the heart beats excessively rapidly, the heart pumps less efficiently and provides less blood flow to the rest of the body, including the heart itself. The increased heart rate also leads to increased work and oxygen demand by the heart, which can lead to rate related ischemia.

Famous quotes containing the word definition:
“According to our social pyramid, all men who feel displaced racially, culturally, and/or because of economic hardships will turn on those whom they feel they can order and humiliate, usually women, children, and animals—just as they have been ordered and humiliated by those privileged few who are in power. However, this definition does not explain why there are privileged men who behave this way toward women.”
—Ana Castillo (b. 1953)
“Although there is no universal agreement as to a definition of life, its biological manifestations are generally considered to be organization, metabolism, growth, irritability, adaptation, and reproduction.”
—The Columbia Encyclopedia, Fifth Edition, the first sentence of the article on “life” (based on wording in the First Edition, 1935)
“No man, not even a doctor, ever gives any other definition of what a nurse should be than this—”devoted and obedient.” This definition would do just as well for a porter. It might even do for a horse. It would not do for a policeman.”
—Florence Nightingale (1820–1910)
