Stress Test (Exercise or Pharmacologic)
A stress test, also known as an exercise stress test or treadmill test, is a medical test used to evaluate the heart’s function and blood flow during physical activity.
It helps diagnose and assess:
1. Coronary artery disease (CAD)
2. Cardiac arrhythmias
3. Cardiac function and performance
4. Exercise-induced chest pain or shortness of breath
Types of Stress Tests:
1. Exercise Stress Test: You’ll walk on a treadmill or pedal a stationary bike while your heart rate, blood pressure, and ECG are monitored.
2. Pharmacologic Stress Test: If you’re unable to exercise, medication (e.g., dobutamine or adenosine) is used to simulate exercise and stress the heart.
Procedure:
1. Preparation: Avoid heavy meals, caffeine, and certain medications before the test.
2. Monitoring: ECG, blood pressure, and heart rate are monitored throughout the test.
3. Exercise: You’ll start with light exercise and gradually increase intensity.
4. Symptoms: Report any chest pain, shortness of breath, or fatigue.
5. Recovery: Your heart rate and blood pressure are monitored after exercise.
Results:
– Normal: No significant changes in ECG, blood pressure, or symptoms.
– Abnormal: Changes in ECG, blood pressure, or symptoms indicating potential heart problems.
Remember to consult your doctor or healthcare professional for specific instructions and to discuss any concerns or questions you may have!
