PVC and Benadryl ???

As a preface to my questions, here is a little information:
I am 36 years of age, 5'11" and 170 lbs.  My B.P. is typically 115/70, and my cholesterol has never exceeded 175.  I work in a high stress environment, and exercise infrequently.  I avoid caffeine, do not smoke, and limit alcohol to 2-3 glasses of red wine a week.
Six years ago, I experienced a short bout with PVC's.  I was diagnosed with a slight Mitral Valve Prolapse and went on my way; my PVC's disappeared within a month.  Seven months ago, they returned with a vengence.  Back to the cardiologist, yielding normal echo (no sign of the MVP!) and good stress test with PVC's during recovery only.  Same story as everyone else.... Dr. says exercise, diet, and relax.... PVC's are harmless.  
A worst case condition (for me anyway) happened the other night.  I awoke at two in the a.m., with heavy chest pain, and PVC's every 3 to 5 beats.  I had pain down my left arm, to the pocket between my ulna and radius, and pain to my little finger.  I got up and around, and felt better in 30 minutes or so.  The next day I called a nurse at my cardiologist's office and described my symptoms.  She told me that these were indications of a harmless situation.  She advised that I take Benadryl in the evening to help me 'sleep through' the PVC's.  I tried it the next evening, and found that I did not experience (or was able to discern) any PVC's that night or the next day.   The following night, I started to have mild PVC's and immediately took a Benadryl.  The PVC's subsided in about an hour, and did not return until late the following day.  
I have started taking a single Benadryl capsule (dosage unknown) in the morning and one at night, and my PVC's have subsided dramatically.  
So now my questions:
1)  I have read that antihistamines can provoke sinus tachycardia, extrasystoles, palpitations, and/or cardiac arrhythmias.  In my instance however, it seems to be beneficial.  Why might this be?
2)  The PVC's do not concern me as much as the pain does.  Even under the effects of Benadryl, there is an underlying mild chest pain that is similar to heartburn.  Several deep breaths causes this pain to abate somewhat.  Is chest pain a normal related  symptom of PVC's?
3)  Benadryl is metabolized in the liver.  What are the long term effects of benadryl use?
Thanks for any help.....
Regards,
Frank.
Some people think that I'm type - A.  But I have the documentation to disprove it.
