How manyextra beats are too many?

[4yroldsmom]

My four year old was diagnosed with pvc's about 2 yrs ago at a routine checkup. At the time we did the echo and it showed no signs of anything wron with his heart and the extra beats were about 15,000 per day.  Now he has increased to about31,000pvc's per day.  Why would they increase and how many is too many.  They ar coming from his right ventricle if that makes a difference.

Am I under the wrong impression that 31,000 pvc's is ALOT even if it's a child?  My EP told me 6000-8000 per day was considered the "normal abnormal" for adults, before they would do anything or treat a patient, have they discussed treatment?

What's his EF?  Did his dr think anything of the increase? Poor little guy, that's alot to handle even for adults, does he have any other symptoms or complain of anything?

Children's heart rates are faster than adults, but if his pvc's have doubled in a year that would make me concerned.  What is his total heartbeats for a 24/hour period?

If you haven't; I would get his records from the doctor so you can have a copy and look them over for yourself.

I can't think of any reason why they'd increase.  Did he have an echo at 2 and again at 4?  would be valuable to know if any volumes or ejection fractions changed.  If these are still normal than it's not concerning.  He might eventually grow out of it.

I too have right ventricular origin (right ventricular outtake tract), and RVOT origin is more common and tend to be benign.

For a 4 year old I think that's about 1 in 5 beats on average is a PVC.  You will hear people with these every 2 beats and not change their heart.  Though over time anything over 10% might be considered for ablation.

If his PVCs are unifocal in his RVOT and the docs feel it might start to be symptomatic, abalation would probably be very successful to buzz out the mis firing pacers in his RVOT.

I hope it runs its course and he outgrows them.  In otherwise structurally normal heart these things are common as heck and do not indicate future disease.
