I am 48 years old and started having heart palpitations a couple of years ago and did a little research and found that they are normal at this age but are not found to cause heart damage. One of the things that I found out is that heart palpitations can be brought on by thoughts of something that is stressful to you and found this to be true so when the palpitations would begin I would change my thoughts to something more pleasant and the palpitations would go away. I would also have the palpitations after drinking a coke or eating a little too much for lunch so I gave up the cokes and have a few snacks instead of lunch and I rarley have them anymore. It might be helpful to keep a diary of what you have eaten before the palpitations or be aware of what you were thinking before the palpitations began. I hope this is helpful!
