Following my most recent thallium treadmill stress test, it took about 8 minutes before my heart rate and blood pressure started to drop, and about 15 minutes before it reached a level low enough for them to take me off the monitor. My heart rate actually increased for about 5 minutes, right after I got off the treadmill and sat down.
Has anyone had a similar experience, and what did your doctors say about it? I have had heart problems for many years, but this is something new. Have appt with doctor to review results, but wanted to see if anyone else had any similar experiences.
I have a totally blocked LAD (bypassed by collateral vessels, provides some help) and severe/moderate mitral regurgitation. The results of my recent test: 1 minute heart rate recovery was 115 beats/min after 5 minutes on the treadmill. Also 1mm depressed ST segment....resolved 5 minutes into recovery. According to my research a depressed ST segment (EKG) indicates deprived oxygen to the heart. I will need bypass and valve surgery in the future, but I am responding well to medication in that heart size is almost normal, my EF is low normal and regurg is improving.
Even with an unhealthy heart my recovery is less than 15 minutes! Fifteen minutes to recover is a long time. Many people have pain with exertion, but it goes away quickly with rest? Your high HR and recovery time may be due to emotional stress!
I would really appreciate additional responses to my question. I'm sure most of the people here have had stress tests, so your results related to heart rate recovery at the end of the test would be very helpful to me. I've done some research, and found a study that indicates that slow heart rate recovery has been tied to decreased survival rate over a 6-year period. As usual, my cardiologist is less than forthcoming with information.
Mt target rate was 147, and actually went up to 155 when I stopped the test and fluctuated between 145 and 155 for a while. Med Tech would not remove those wonderful pads from my chest until I got to 110, which took about 12-15 minutes as I recall. Was in sitting position.
I'm not in the best conditioning shape, but walk 2 - 3 miles a few times per week. Have had two heart attacks and three stents.
How much time before you reached your HR target? Was the test terminated due to pain or fatique? Was there any chest discomfort? Do you have any pulmonary issues?
Anxiety and apprehension can cause a faster than normal HR post test. Obvioulsy, you have had prior tests. Is this last result different from past test results? Do you have SOB or pain when you walk 2 to 3 times a week?
I thought may recovery time of 5 minutes was long but I exercise (weights and aerobic 3 times a week) and have known CHF and MVR so I expected abnormal results. Fifteen minutes recovery demands an explanation from your doctor.
I am super-new at this--just had my first stress test 2 weeks ago, and doctor hasn't gotten to interpret it all for me. But I have the results--it looks like it took my heart 4 minutes and 8 seconds for 'recovery' -- but I sure don't know what that really means. All I know is that I felt like I was going to DIE on the treadmill, my heart was beating so hard and fast and I got so out of breath--that awful feeling lasted for several minutes, but not 15, yikes!
