7. Pharmacologic stress test: Medication is given through an IV line in your arm to dilate the arteries, which increases your heart rate and blood flow, like the effects of exercise. This test may be done in combination with nuclear imaging, echocardiography, or MRI.

Reasons for the test:

• Determine the cause of chest pain, shortness of breath and weakness
• Find evidence of inadequate blood flow to the heart muscle during exercise
• Monitor or diagnose blockages in the coronary arteries
• Assess risks for a heart attack

8. Tilt test: Often used to determine why you feel faint or lightheaded. During the test, you lie on a table that is slowly tilted upward. The test measures how your blood pressure and heart rate respond to the force of gravity. A nurse or technician keeps track of blood pressure and heart rate (pulse) to see how they change during the test.

Reasons for the test:

• Assess dizziness or fainting spells
• Identify heart rhythm changes
