Hyperthyroidism: Excess thyroid hormone Excess thyroid hormone also causes the heart to beat harder and faster and may trigger abnormal heart rhythms. One is atrial fibrillation, a disorganized rhythm in the heart's upper chambers. A related symptom is palpitations, a sudden awareness of your heartbeat.

This is because the flow of potassium in and out of heart cells helps regulate your heartbeat. Low blood potassium levels can alter this flow, resulting in heart palpitations ( 14 ). In addition, heart palpitations may be a sign of arrhythmia, or an irregular heartbeat, which is also linked to potassium deficiency.

They usually aren't serious or harmful, though, and often go away on their own. Most of the time, they're caused by stress and anxiety, or because you've had too much caffeine, nicotine, or alcohol. They can also happen when you're pregnant. In rare cases, palpitations can be a sign of a more serious heart condition.

A serious problem called thyroid storm can happen if Graves' disease is not treated and you have too much thyroid hormone. The buildup of thyroid hormone causes severe restlessness, fever, confusion, sweating, and diarrhea. Your heart may beat very fast and your blood pressure can get very high.

A healthy thyroid plays a vital part in brain chemistry, so we should not be surprised that a thyroid disorder can cause unpredictable mood changes. For example those with an overactive thyroid (hyperthyroidism) can suddenly feel tense and anxious.

Thyroid hormone influences the force and speed of your heartbeat, your blood pressure, and your cholesterol level. As a result, a malfunctioning thyroid gland can cause problems that masquerade as heart disease or make existing heart disease worse.

Conversely, hypothyroidism occurs when the thyroid gland is underactive and does not produce enough hormones. Hypothyroidism can weaken the heart muscle and heart rate, reducing the heart's pumping capacity and increase the stiffening of blood-vessel walls. The combination of these changes can lead to hypertension.

Heart palpitations are a direct result of lower levels of the female hormone estrogen, which leads to an overstimulation of the heart. Such a drop in hormone production can be linked to an increase in both heart rate and frequency in palpitations, and non-threatening arrhythmias.
