10 Graves' Disease Symptoms
Reviewed: Dr. Mera
Symptom #9: Palpitations
Palpitations occur when the individual perceives that there is an abnormality of their heartbeat due to the awareness of the cardiac muscle contractions. It can occur due to many reasons such as anxiety and cause issues such as breathlessness, sweating, dizziness, chest pain, and headaches.
In Graves’ disease, the excessive levels of thyroid hormones can cause changes in the nervous system’s control of the heart. Patients can experience palpitations due abnormal heart rhythms such as sinus tachycardia (abnormally fast heart rate that tops 100 beats per minute) and atrial fibrillation. Atrial fibrillation is an irregular heart rhythm that is seen in 5 to 15% of patients with hyperthyroidism.
