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)
