However, palpitations may signal a serious condition, especially if they are caused by an arrhythmia . Symptoms of palpitations have been described as a flopping sensation in the chest and throat. It is rarely painful but usually associated with anxiety. Palpitations can be associated with the sensation of a rapid heart rate. The determining factor is the nature of the palpitations, how long the runs are, and the location of the palpitations in the heart.
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. Diagnosis of the cause of palpitations starts with a history and physical exam. Many times the palpitations have stopped by the time the person seeks medical attention.
