Often the cause of your heart palpitations can't be found. It's thought that common causes of heart palpitations include:
- Strong emotional responses, such as stress or anxiety
- Strenuous exercise
- Caffeine
- Nicotine
- Fever
- Hormone changes associated with menstruation, pregnancy or menopause
- Taking cold and cough medications that contain pseudoephedrine, a stimulant

However, occasionally heart palpitations can be a sign of a serious, underlying problem, such as an overactive thyroid gland (hyperthyroidism) or an abnormal heart rhythm (arrhythmia).
Many physician's dx heart palpatations as stress related which includes anxiety.
