Basis of Stress Test
Target heart rate
Refers to the desired heart rate that the patient should achieve during the test.
Target heart rate
Supporting element for THR; the patient can’t achieve the THR (strengthens the heartbeat).
Digoxin
Reserve for patients who are unable to exercise adequately.
[stress test]
Pharmacologic stress test
Done after exercise stress test.
[stress test]
Pharmacologic stress test
Demonstrated in patients with decreased functional capacity or in patients who cannot exercise.
[pharmacologic]
Induced by pharmacologic agent
[3] Drug used
- Adenosine
- Dypyridamole
- Dobutamine
adenosine analog.
Regadenoson
Increase the blood flow.
Vasodilating agent
