Brief Answer: Hi and welcome to XXXXXXX Detailed Answer: Thanks for the query. This is moderately decreased TSH but this is not urgent condition. You should see endocrinologist and find the right causes of low TSH. Most commonly this is some autoimmune disease or thyroid adenoma. 3.3 is low potassium,but this is not significant fall too. It can be treated by standard oral supplements and you should check its level again in 2 days. Both TSH and low potassium can be cause of heart palpitations,but some serious consequances rarely happens. However,you should keep your potassium level within normal range by dietary changes or if there is persistant decrease,then you should check your kidney function. Wish you good health. Feel free to ask. Regards

Brief Answer: hi Detailed Answer: Low potassium can be caused by hyperthyreidemia and it means that there are elevated levels of thyroid hormones. So you may be taking to much synthiroid. Tsh dont have direct effect on potassium.
