Hello everyone. I have recently joined this nice family and found so much good information - some of which (I admit) also scared me. I had a few AF episodes last year but I didn't know what it was. It would go away after 5-6 hours. This year I had probably just two going into April and when I mentioned it to my GP he gave me Bisoprolol to take if I get another episode. No AF word was mentioned EKG was good. Soon the perfect storm started. Sciatica hit me so hard that I couldn't sit for more than 5 seconds. It was even worse in bed. Sleeping pills were the only help. After two weeks of torture and exhaustion my heart started to beat so irregularly and hard - Bisoprolol no help. After 3 days of (on and off) AF I finally called the ambulance and then I was admitted into hospital after emergency room.
The blood test showed low TSH (thyroid reading) of 0.116 (std range 0.358-3.74).
The EP dismissed it as probably the lab error and informed about what AF is.
He prescribed Flecainide to carry with me and to take 3 if another episode starts.
Sure enough, 10 days later another AF. This time I was so scared so I called emergency again. This time, the blood test shows TSH reading of 4.24 - above high standard limit. My EP dismissed it again as "crazy emergency room lab".
I read that thyroid could be connected with AF and I insisted that we take the full thyroid test (TSH, T3 and T4).
This time it comes normal but T3 and Free T4 right at the bottom of the standard range. The EP gleefully says "You see, I told you, thyroid is OK." He prescribes Flecainide twice daily. So, I've been AF free for the last 3 weeks.
I went to another GP and she ordered all tests. All blood thyroid tests were normal.
However, the ultrasound reveals "Left thyromegaly with complex nodule 1.2x0.7x1.1 cm". She wants biopsy done.
My world fell apart at that moment. My hands started trembling and my head was shaking. That was too much to handle. I am now on antidepressants. My dilemma is whether to go and have biopsy. I heard that 90% of time it comes as non malignant but still...
One member said that ablation should be done early. My question is: If ablation should be done early why bother with Flecaidine and other medications?
Sorry for such a long story. Thank you for reading.
