Font Size

Causes of Heart Palpitations

Many things can cause heart palpitations. In the vast majority of cases, the cause is either related to your heart or is unknown. Non-heart-related causes of palpitations include:

If you have heart palpitations after eating certain foods, the problem could be food sensitivity. Keeping a food diary can help you identify which foods to avoid.

Palpitations can also be related to underlying heart disease. When they are, palpitations are more likely to represent arrhythmia. Heart conditions associated with palpitations include:
