It depends on the type of irregularity. If it is atrial fibrillation then you need to be on slowing down drugs, but if the irregularity is simple ectopic beats (atrial or ventricular) and they don't worsen with exercise, then mild to moderate exercise is fine. Really hard exercise - iron man marathons are not good for the heart, no matter how fit it is. Best discuss with your doctor on what you have.

Most people's heart never beat completely regularly. Almost everyone has additional beats called ectopics, which are quite benign, and the more you worry about them, the more you get, but they do no harm at all and rarely are related to any heart problem. Sometimes the heart can develop atrial fibrillation, which can only be detected by an ECG. This does require some heart tests, and often drugs, including anticoagulants, are needed. But most irregular heart beats are quite benign.

There are many causes of chest pain, most of them benign. If they are only associated with exercise, then they could be related to your heart, but we have lungs, pleura, muscles, and other tissues, all of which can cause chest pain as can some forms of indigestion. I think you need to see a doctor about it if it is worrying you.

There is huge debate on heart and the diet. Doctors for years have said that saturated fats are bad, but there is not a lot of evidence for this, and some are even suggesting the ketogenic diet which is high fats. What you need to avoid are trans fats (found in many processed food), and most other food taken in moderation do not damage the ehart or its arteries at all.

If it is just your fingers, then there is a condition called Raynauds phenomena, which is due to spasm of the small arteries and is often hereditary, and nothing to worry about. Some people just have cold hands, but at 21, I doubt if it is a circulation issue. See your doctor and ask him to check your arm pulses if you are worried.
