Difference between "open wounds" and "prevent monster heal"

I looked on Arreat Summit but could not find where the specific characteristics of these two abilites are. Reason I ask is this: merc has Duress armor which has 33% chance of Open Wounds and his Bonehew has Prevent Monster Heal. Do these work similarly? And if this is a noob question, sorry, but I never looked at this before.

My guess would be that
open wounds = like poison...
Prevent Monster Heal= Doesn't let the monster heal....

Open wounds works in pvp. The dmg it inflicts per second is based on level. You hit the open wounds break point at lvl 90.

Prevent moster heal is just that. The monsters dont regain any health that they would hav normally.

Oh, it does not work in PvM?

It works in PVM as well. I meant that to be like "Unlike prevent monster heal, this works in pvp as well as pvm"

Okay, okay, sorry about the quote thing. I was in a hurry and not paying attention.
