Exercise provocation tests
Patients ingested the maximum desensitization dose and underwent either
a free running or treadmill ergonometric stress test or a stepping
exercise test after 30 minutes. The EPT was performed for at least 15
minutes, with a target heart rate of >180 beats/minute.
Patients with negative EPT results were instructed to exercise after
ingestion at home to confirm the negative result. Patients with positive
EPT results underwent repeat EPTs after a period of time (usually about
2 years) according to the physicians’ and families’ discretions to check
for remission.
