STRESS TEST RISKS

A stress test, also called an exercise stress test, is used to gather information about how well your heart works during physical activity. Because exercise makes your heart pump harder and faster than it does during most daily activities, an exercise stress test can reveal problems within your heart that might not be noticeable otherwise.
An exercise stress test usually involves walking on a treadmill or riding a stationary bike while your heart rhythm, blood pressure and breathing are monitored.
Your doctor may recommend an exercise stress test if he or she suspects you have coronary artery disease or an irregular heart rhythm (arrhythmia). An exercise stress test may also be used to guide your treatment if you’ve already been diagnosed with a heart condition.
An exercise stress test is generally safe, and complications are rare. But, as with any medical procedure, it does carry a risk of complications.
Potential complications include:

-Low blood pressure. Blood pressure may drop during or immediately after exercise and cause dizziness. It usually goes away when you stop exercising.
-Abnormal heart rhythms (arrhythmias). Arrhythmias brought on by an exercise stress test usually go away shortly after you stop exercising.
-Heart attack (myocardial infarction). Although very rare, it’s possible that an exercise stress test could provoke a heart attack.
