I did have one done. The doctor said everything was fine but noted an enlarged spleen. I really had to complain with chest pain before my doctor would request the holter test.
You need to ask your doctor what to do next. Your average heart rate is too fast which is not healthy for your heart. An average of almost 110 could, if it's representative for your normal heart rate, also have a cause which must be found (or ruled out).
You also have a lot of premature/ectopic heart beats. It's usually not dangeous but it should be investigated when you have thousands of them.
Have you had an ultrasound of your heart done?
