ST depression may occur in ischaemic heart disease:
- indicates myocardial ischaemia, and may be associated with the discomfort of angina
- rest leads to a reversal
- it is not a sign of infarction
Other causes of ST depression include (1):
- biochemical causes
- hypokalaemia
- hypocalcaemia
- hypomagnesaemia
- digoxin
- glycosides can produce ST depression in the electrocardiogram, both in patients with cardiac disease and in healthy individuals.and in healthy individuals
- the ST depression that may secondary to cardiac glycoside use complicates the interpretation of rest and exercise electrocardiogram (ECG)
- left ventricular hypertrophy
- hypothermia
- stroke (especially subarachnoid haemorrhage)
