What causes an irregular heart rate?

My doctor said mine is irregular but doesn't seem concerned.

A common scenario is that some cardiac muscle has died(eg due to lack of oxygen to that muscle) and the signal for the heart to contract gets delayed because it has to go around that dead muscle. Thus, the heart does not contract in its classical lub-dub rhythm.

I believe that consuming caffine could play a very important role in the heart rate. Many drinks and foods contain caffine such as orange and dark flavored sodas. Also chocolate.
