Our expert says:
Thanks for your question. If your heart is beating fast, then the important questions are how fast, and why it is beating so fast. Most often if your heart is beating fast it is because your body is instructing it to do so, for example if you are anxious or exercising or have a fever.
Your doctor should be able to find out why your heart is beating fast and whether it is necessary to do anything about it. Usually it is a very benign condition which does not require treatment.
Best wishes. JT
