Hi,
Welcome to the ehealthforum and I am glad to help you out. If any medications are required, then you can be put on them and then the stress test can be done. If you have not been prescribed as yet, then probably you donât need them. However, beta blockers are avoided as they interfere in the stress test. If you have been prescribed any beta blockers (atenolol, metoprolol etc), then these should be stopped at least 48 hrs before the stress test. The stress test gives a decent idea about the performance of the heart under stress.
I sincerely hope this information helps. Take care.
