Prevention is related to the cause. For example, if palpitations are caused by anxiety, the use of an anti-anxiety medication may prevent this condition. Avoiding the precipitating factors such as certain medications, coffee, tea, or alcohol can prevent palpitations. Many causes cannot be prevented.
Sometimes palpitations may be a warning sign of underlying heart disease. If palpitations are caused by a problem with the heart, death can occur if the condition is not diagnosed and treated. In children, palpitations are usually more of a nuisance than a medical problem.
There are no risks to others.
