Thanks for asking your question - (a side note - a little tough to follow due to lack of punctuation).
Chronic diarrhea can be caused by malabsorption, infection or inflammatory bowel disease. I would assume that you have had a colonoscopy in the past, which can rule out most of the more common diseases. I would test the stool for infection, as well as various malabsorption syndromes.
Regarding the PVC's. This can be evaluated by a cardiologist. If you are having chronic diarrhea, electrolyte abnormalities can be considered. I would look at the potassium and magnesium levels in particular. If normal, you can consider an event monitor or holter monitor to document any arrhythmia. An echocardiogram can be considered to look for any anatomical abnormality.
You can discuss these options with your personal physician.
Followup with your personal physician is essential.
