Glossary for Tachycardia

  • Acarophobia: An exaggerated or irrational fear of mites, ticks, small insects and worms.
  • Achluophobia: An exaggerated or irrational fear of the night or darkness.
  • Achrestic anemia: Achrestic anemia is a form of anemia similar to that caused by Vitamin B12 deficiency but it doesn't respond to treatment with Vitamin B12. The condition tends to progress slowly and can result in death if not treated. There are a variety of possible causes.

  • Acute Renal Failure: Syndrome characterised by rapid decline in kidney function with accumulation of waste products in the blood, occurring over a period of days to weeks

  • Acute radiation sickness: Tissue injury can result from exposure to radiation. The radiation dose, rate of dosing and tissues irradiated will determine the severity and type of symptoms. The effects may be chronic, delayed or acute. Acute irradiation sickness usually occurs after abdominal irradiation and lasts for hours or days.
  • Acute stress disorder: An acute anxiety state
  • Adrenal Cancer: A malignant cancer that develops in the adrenal gland. The tumor may be nonfunctioning (does not produce hormones) or functioning in which case excessive levels of hormones can cause a variety of symptoms depending on which hormone is involved. Adrenal hormones made in the cortex (outer part of the gland) are aldosterone, corticosteroids and androgenic steroids. Adrenalin and noradrenalin are the hormones made in the medulla (central part of the adrenal gland).
  • Adrenal adenoma, familial: A benign tumor that develops in the adrenal gland and tends to run in families. The tumor may be nonfunctioning (does not produce hormones) or functioning in which case excessive levels of hormones can cause a variety of symptoms depending on which hormone is involved. Adrenal hormones made in the cortex (outer part of the gland) are aldosterone, corticosteroids and androgenic steroids . Adrenalin and noradrenalin are the hormones made in the medulla (central part of the adrenal gland).
