Calcification of thyroid nodules alone does not cause palpitations, but palpitations may occur when accompanied by hyperthyroidism.
Simple thyroid nodules with calcification usually do not have obvious symptoms, unless the nodule is too large and produces localized pressure symptoms, such as dyspnea, dysphagia, hoarseness, etc., and usually do not have symptoms of palpitations.
However, if the nodule has the secretion function which leads to hyperthyroidism, then the body may show high metabolism, and then the symptoms of tachycardia may appear, resulting in palpitations, and may be accompanied by emaciation, fatigue, hyper appetite, diarrhea and other symptoms.
Patients with palpitations who have thyroid nodules with calcification are advised to go to the hospital and ask the doctor to make a judgment.
