It's a possibility, especially if you have a good number of PVCs.  



Last May I was diagnosed with cardiomyopathyCardiomyopathy
Dilated cardiomyopathy
Hypertrophic cardiomyopathy
Peripartum cardiomyopathy
Restrictive cardiomyopathy (E/F of 30%).  It was later discovered that I had roughly 45,000 PVCs per day.



BackBack pain - low
Back strain treatment in '96 a doctor found that I was having PVCs.  He dismissed it and told me that they were benignBenign ear cyst or tumor
Benign positional vertigo (in many cases they are).



If you're concerned, see your doctor.  Don't wait too long.  A doctor can measure PVCs through the use of a HolterHolter monitor (24h) monitor.  A HolterHolter monitor (24h) is like a mini EKGAtrioventricular block, ekg tracing
Ecg
Exercise stress test, about the size of a Walkman, that you wear for a day.



As for the research, my doctor knows of only one study done regarding PVCs and heartCongenital heart disease
Cor pulmonale
Coronary heart disease
Cyanotic heart disease
Depression and heart disease
Heart attack
Heart attack first aid
Heart attack symptoms
Heart bypass surgery
Heart bypass surgery - series
Heart disease failure.  I don't have any references that I can point to, but according to him, some of the patientsKidney diet - dialysis patients in the study had 15,000 to 23,000 PVCs per day.

I went through an unsuccessful ablation procedure last summer.  (Unsuccessful because it did not elimate the PVCs.)  My doctor then put me on Amiodarone, which is lessening the PVCs a good deal.  My doctor estimates that I now have 15,000 PVCs per day, although he did not confirm that with a HolterHolter monitor (24h).



I remember very clearly discussingDiscussing death with children with him the chicken-and-egg problem you mentioned.  Although it's too early to tell we're cheering on the egg.  ;-)

I also have PVCs and after all the test I am absolutely terrified of climbing on a treadmill.  Over the last several months I have had an EKGAtrioventricular block, ekg tracing

I have had pvc's,pac's since about 13 but now at 53 they have become much more frequent and bothersome. All my life during excercise I would have a few, just like you but never gave it much thought. During my younger days I would run 5 miles a day and workout with weightsDifferent types of weight gain
Exercise and weight loss

Height/weight chart
Losing weight
Roux-en-y stomach surgery for weight loss
Weight gain - unintentional
Weight loss
Weight loss - unintentional
Weight loss and age 3-4 days a week and this went on for near 30 years. Never were the palpitationsHeart palpitations a danger. Now however I have at least a thousand per day, every minute of the day and believe me they are a bother. There are people who live normal lives with 25,000 a day which I find amazing.



I hope yours will resolve themselves and if the docs and tests are ok, then no need to worry. You have a whole lifetime ahead of you and the palps should be the least of your worries even though its easier said than done. Go ahead and workout, the quicker you put your mind to other things the less you will notice the palps especially if you are only having a few per day.



Good luck.
