I am 64 and have been under a great deal
Can I see the EKG?
Stress and caffeine would increase heart rate and lead to irregularities. It can as well precipitate ischemic changes in preexisting conditions. I would like to review the EKG report to see if there any ischemic changes. If there are any, then the doctor is right in asking for stress test.
You may get the test done when calm; but the results will not change the fact there were ischemic changes (if it has been found) during stressful condition and after caffeine.
In simple words, stress test is essential if there are changes found in the EKG. There is an option to upload reports and pictures on this page. If you wish you may upload the EKG and let me check.
Hope this is clear. Let me know if you need clarifications.
