During the test the patient's various symptoms and blood pressure response is repeatedly checked. When using the ECG and the blood pressure monitoring by itself the test is called a cardiac stress test or an exercise stress test.Besides these, the test is also called as an exercise treadmill test or an exercise tolerance test or a stress test or an exercise ECG test.hen it is compared to the blood flow that occurs during rest, the stress test reflects the imbalances of the blood flow to the individual's heart in particular the left ventricular muscle tissue.

A single lower-than-normal reading is not cause for alarm if you are not experiencing any other symptoms or problems. However, a sudden drop in blood pressure --- even a change of just 20 mm Hg --- can cause dizziness or fainting.Sometimes a rapid decrease in blood pressure can indicate an underlying problem such as:f you have gotten dehydrated, have low blood sugar or have spent too much time in the sun or a hot tub, it is more important to recognize how quickly your blood pressure drops than how low it drops. Keep a record of your symptoms and your activities at the time your symptoms occurred.
