Stress tests are an important tool to find underlining conditions that may not normally be found when at rest. Comparisons are made between a heart at rest and under stress. Some differences that may be seen are include in the electrical signals in your heart, how much blood your heart is pumping, how much blood is flowing in your arteries and veins.
