nodules and heart palpatations

[needanswers452]

HI Dr.

As of the last year, I have been experiencing PVC's, flutters and a high heart rate. My TSH is .66. All my heart tests have come back normal.  I had a thyroid ultrasound which showed several nodules:

Impression: The left thyroid lobe contains both solid and cystic and complex lesions and exhibits increased vascularity on interrogation with color doppler. The appearance would be consistent with collide nodules with varying degrees or cystic degeneration. Follow- up is mandatory at 6 mths, 12 mths and 2 years.

Is it possible that these nodules could be producing extra thyroid hormone and causing the heart problems. I am really at my wits end with what is going on with me. Any insight would be appreciated. Should I have further tests to find out if these nodules are cancerous. I'm 28 female, and planning on having a family soon.

Thank you

also consider TPO and Tg antibody testing, particularly with plans for pregnancy in the future.

The TSH suggests that the thyroid is not the likely cause of the PVC.  Would see an endocrinologist about the nodules/cysts to see if FNA biopsy is needed.  Otherwise consider a follow-up TSH test to make sure there is not a trend towards hyperthyroidism (ie, low TSH).
