Many types of heart palpitations are harmless and do not need any type of first aid care because they go away on their own, according to the National Institutes of Health's MedlinePlus. It is necessary to contact an emergency medical professional if the person loses alertness, experiences shortness of breath, has chest pain, is sweating profusely or experiences dizziness or lightheadedness.
There are many factors that can contribute to heart palpitations including stress, smoking and caffeine. Medical conditions such as anemia, low blood sugar, thyroid disease and dehydration can also cause someone to experience heart palpitations, according to WebMD. If someone is experiencing heart palpitations frequently, it's important for them to seek medical attention to ensure they do not have a serious illness that is causing them. A doctor can determine the cause of the patient's heart palpitations using an electrocardiogram, a Holter monitor, an echocardiogram and coronary angiography.
There are numerous lifestyle changes that can prevent heart palpitations if a serious medical condition has been ruled out. Regular exercise, eliminating caffeine, avoiding nicotine and practicing relaxation techniques can all aid in preventing heart palpitations. It is also important for individuals with harmless heart palpitations to try not to worry too much because this can cause them to worsen.
