NUCLEAR CARDIOLOGY STRESS TEST

The preparation for the patient is thus:
- no breakfast so that less splanchnic blood flow
- medication restrictions:
3 days - perhexiline, viagra
2 days - BB, nicorandil
1 day - CCB, nitrate

Things that may happen to the patient with the tracer:
-nausea & taste perversion
- techy tinnitus
- allergic reaction
- excreted in the breast milk. It decays such that only 12.5% of the original dose is left after 24 hours.



What this has in common with all exercise tests is the preparation of the skin:
- shave hair
- wipe skin to remove oils
- scrub skin to remove dead cells and thereby increase conductivity

If you are not getting a signal then:
- sticky-tape the electrodes
- move the subclavian leads closer together

What is different from the ordinary stress test is that you always have to wait for 15 minutes afterwards before you image because:
1. In Thallium get diaphragmatic creep
2. In Tc get subdiaphragmatic activity masking the heart. This is also why you give them a glass of something straight after exercise.
