A 21-year-old member asked:

Once I start on supplemental oxygen, will I have to stay on it? Or, will I become addicted to supplemental oxygen?

No: There is no description of an oxygen withdrawal syndrome (providing one maintains an appropriate minimum oxygen level) presumably the net benefit of chronic oxygen outweighs the net side effects so a necessary aspect of addiction does not exist.

When you have 3rd degree block, it's completely discordant (ie nothing is working together) . When the different parts of the heart are doing their own thing without communicating properly, it's life threatening and requires a pacemaker
