I don't have a specific theory as to why this occurs, but there may be an association with the vagus nerve that innervates the heart and portions of the digestive system. PAC's are a benign condition, but certainly PAC's can cause discomfort and concern for the patient that suffers from them. Treatment with a beta blocker like Tenormin can reduce the frequency of PAC's and eliminating tobacco, caffeine, and alcohol also can help. Thus, you may want to investigate medications like zantac, tagamet, or pepcid which decrease the acid secretion in the stomach and immodium which can be used to treat irritable bowel syndrome. I hope you find this information useful.
