Arrhythmias

[Ocean3000]

I know PVC's and PAC's are normal but I would like to know what it means when they state "occasional" are normal?  What is considered occasional?  Is it 1 a minute, 1 an hour, 1 a day or 1 a week?  I can't find anything that actually tells me what is normal?

I think it's a bit different.

For PVCs it's not the frequency that is important and that determines if they are normal or not, it's their origin, morphology, timing, coupling, interval, patterns, w/wo exercise, heart disease or not, etc.

PACs are somewhat different, they are almost always benign anyway.

Regarding your question, I think the grades are: None - Very rare - Rare - Occational - Frequent - Very frequent.

I think (but every doctor have different definitions it seems) that none are none, Very rare is less than 10, rare is less than 250 or so, occational is less than a couple of thousands, frequent is less than 10.000 and very frequent is more than 10.000 (but it differs greatly)..

Sorry this answer probably wasn't very helpful :(
