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, possibly causing you to feel dizzy or faint. The problem should resolve after 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 exceedingly rare, it's possible that an exercise stress test could provoke a heart attack.
