I will tell you something a doctor on the other heart board told me. Winston Churchill once said: "I recall the old man on his deathbed who said 'I had a lot of worries in my life, many of which never happened'"
PVCs with a normal EKG and echo is not associated with a significant increased risk of cardiavascular events.
It is true that almost everyone has PACs and PVCs a day, most people do not feel them or ignore them. Some people are much more sensitive to them.
A beta blocker may help decrease the symptoms and might be worth a shot. The same is true for calcium channel blockers. If medications don't improve it, I would recommend conservative treatment. Procedures are reserved for very symptomatic patients with a good likelihood of a successful procedure.
PACs and PVCs can increase in frequency around pregnancy and post partum. It often gets better.
If you read back in the posts, you will find that you are clearly not alone. This is a very common problem and your concerns are common. I agree with what your doctor told -- these are very low risk. People with normal hearts do not drop from PVCs. I rarely get PVCs. I don't know how many I would have and I know not to worry about them.
If you are concerned you can ask for a second opinion, but I think the second opinion will agree as well.
I hope this helps.
