Risks
By Mayo Clinic staffAn 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.
