Is stress (or other) test necessary?

I am a 51 year-old male with a history of bipolar disorder. For years, I’ve taken a number of medications that can produce cardiac symptoms (Eskalith, Celexa, to name two).  But until I started taking Synthroid recently for lithium-induced hypothyroidism, my annual electrocardiograms always came back negative.  Now, there is evidence of PVCs (arrythymias).

I went to a cardiologist and he said that, as a precaution, I should have a stress test.  But is this really necessary?  I don’t even notice the PVCs; I have no other symptoms; and there are no cardiac (or other serious problems) in my family – happily, longevity is the rule, not the exception.

I do not like unnecessary tests.  I would appreciate your comments.

That is a tough one.  The decision is made based on the history and physical exam and evaluation of your risk factors.   For someone your age, I could understand your doctor wanting to see a stress test.

It is always your decision as to whether you decide to do it.  What I will tell my patients is that I recommend it even though I think it will be negative and leave the decision to them.  There are risks to doing and risks to not doing it -- there is not always a right or wrong answer.  I think that is the position you are in and you can make an argument for either case.  I recommend asking your doctor why they think it is necessary and base your decision on the answer.

I hope this helps.  Thanks for posting.
