poetry lyrics: The Bruce treadmill test starts out real slow./ If you're fit through three
 stages you go./ But you puff and you snort,/ And your heart rate falls short -- /
 Can't inject and then image peak flow.
You're in luck -- In the Nuclear Lab,/ Dipyridamole vials we can grab./
 Not dependent on rate,/ They just vasodilate;/ But next week,
 hit the gym, work off flab!

Tests of myocardial flow in the Nuclear laboratory, e.g. gated SPECT, require a stimulus so that the specific radiotracer can be injected at peak blood flow to image the state of heart muscle. Ideally, exercise stress, as with a submaximal treadmill procedure, provides this stimulus, with a high attained heart rate reflecting success. As a backup in those unable to exercise sufficiently, (musculoskeletal or breathing problems, reduced fitness), pharmacologic stress may be used. Dipyridamole ,tradename Persantine, is a commonly used agent for this purpose, increasing blood flow optimally, but with little change in heart rate or blood pressure.
