- Hyperthyroidism is a disorder in which the thyroid gland produces too much hormone and speeds up your metabolism. One of the main symptoms of hyperthyroidism is a rapid heartbeat and heart palpitations.
- A common form of hyperthyroidism is called Graves disease, and it is often associated with atrial fibrillation or irregular heartbeat.
According to ABC News Health, "The classic arrhythmia with hyperthyroidism is atrial fibrillation." - Hypothyroidism, an underactive thyroid, is the most common of the two disorders of the thyroid. In this case the thyroid gland does not produce enough hormone, and your body functions, including your heart, slow down.
- Hypothyroidism causes an increase of bad cholesterol in your blood. This can cause plaque to build up in your arteries, narrowing them. The blood returning to your heart slows down, leading to heart disease and sometimes heart failure.
- Hypothyroidism can lead to an enlarged heart, which is detected by a chest X-ray.
