Your Questions About Treadmill Exercise Test | Exercise for Health ...

Lizzie asks?

My BP went from 125/ 80 to 149 /49 on a treadmill stress test, What does this mean?

The information available on the net says that diastolic BP shouldn?t change that much during exercise

bobg answers:

Sadly, the readings mean something quite different from what your two other Answers say. Your ?mean pressure? fell drastically under stress, instead of rising to cope with it. It would have been helpful if you?d been able to state what your pulse-rate did at the same time because your pressures are only half of the story.
Also, -did you begin to feel angina pain?

Your ?mean pressure? dropped from 125 to 82 and it did this because more blood was being permitted to pass down and through your arteries than was being pumped back in to replenish them. This was the direct result of impaired cardiac ability.

It?s true that if your heart is fit, healthy, and capable of doing its task, then it will maintain diastolic pressure (or even slightly increase it) under stress. And because ?mean? is simply ?diastolic plus a little bit? ,-in practice-, it too should stay the same under stress. Yours didn?t, and unfortunately it means there is something amiss, which, if possible, should be identified and put right.

Under went a treadmill test and felt disappointed Need help?

I took a treadmill test last week. It came with the impression No significant ST-T changes and TMT is negative. There was no doctor nearby other than the technician and I got the report signed by the doctor. My max HR achieved was 94% and my max pressure was 160/90. Initial BP value is 120/80. Total exercise time is 10 mins. Not satisfied with test because BP was not taken at regular intervals but it was hooked up in the report. I repeated the test in another hospital where they took the BP initially and at the end only. The initial value was 130/90 and the final BP was 180/100 and I achieved 97% of the max heart rate. The impression was negative TMT for inducible ischemia. But they mentioned minimum ST-T changes during exercise and BP response is hypertensive.
Background history about me:
I am a non smoker, non drinker, no diabetes, no hypertension (at rest), no obesity, normal lipid profile and no early family history of heart attacks. Known MVP. I get frequent chest pain (any time no specific pattern).
During both the test I felt giddy after the max HR and vanished after recovery. Why BP was not monitored properly in both the cases. In the first case may be three or four times whereas in the second case in the beginning of the exercise and at the end. Why minimal ST-T changes was mentioned in the first whereas not in the second. Hypertensive response was mentioned in the second but not in the first. Why all these discrepancies. Why such a slackness while doing these important tests in hospitals. Why a doctor was not there in the first case?
What do now? Can I speak the above said details openly to my cardio? Will he accept it?
As I told above I took this treadmill test for frequent chest pains(not any specific pattern). My BP rose to 180/100 in the second TMT test. They took initially and at the end.
They haven?t mentioned anything like VO2 max. These tests were done in Chennai, India and I don?t know any rehab centers. The second test was done in a famous hospital which is well known for heart surgeries.

bobg answers:

A doctor should have been present while doing tmt, i don?t know which hospital you underwent these procedures, talk to your cardio, i don?t think there is reason to panic about the results.

Mary asks?

What is the average Bp when exercising.?

My Bp went to 236/168 on a treadmill exercise test today. I had no chest pain but a pain up the front of my neck. Was this blood pressure high? Also was the pain in my neck related to the exercise or could it have been my heart, as i have this pain after i have chest pain.

bobg answers:

Was this a ?self test? or one supervised by a doctor or cardiologist? If it?s a self test I would advise you to see a doctor before getting on a treadmill again. In fact, see a doctor anyway. That?s a very high blood pressure. An increase in diastolic blood pressure of more than 10 mmHg (optimal is <120) during or after exercise represents an unstable form of hypertension, and may be associated with coronary artery disease. At 236 you could be classified as well above third stage hypertension. Really, see a doctor.
