CODE 2     Positive

On an exercise tolerance test, the patient developed either:

a.  Both ischaemic discomfort and ST shift greater than or equal to 1 mm (0.1 mV) (horizontal or downsloping); or

b.  new ST shift greater than or equal to 2 mm (0.2 mV) (horizontal or down-sloping) believed to represent ischaemia even in the absence of ischaemic discomfort.

On cardiac imaging investigation (e.g. exercise thallium or MIBI test, stress echocardiography, or dipyridamole, thallium, or adenosine radioisotope scan):

a. Evidence of reversible ischaemia on nuclear imaging of the myocardium.

b. Evidence of inducible ischaemic response during echocardiographic imaging of the myocardium.

If the patient had an equivalent type of exercise test but  a definite evidence of ischaemia on cardiac imaging (e.g. an area of clear reversible ischaemia), this should be considered a positive test.

CODE 3     Negative

No evidence of ischaemia (i.e. no typical angina pain and no ST shifts).

CODE 4     Equivocal

Either:

a.  Typical ischaemic pain but no ST shift greater than or equal to 1 mm (0.1 mV) (horizontal or downsloping); or

ST shift of 1 mm (0.1 mV) (horizontal or downsloping) but no ischaemic discomfort.

b.  Defect on myocardial imaging of uncertain nature or significance.
