Beta blockers. Beta blockers, also called beta-adrenergic blocking agents, treat a variety of conditions, such as high blood pressure and migraines. Find out more about this class of medication. Beta blockers, also known as beta-adrenergic blocking agents, are medications that reduce your blood pressure.

The Vikings came from three countries of Scandinavia: Denmark, Norway and Sweden. The name 'Viking' comes from a language called 'Old Norse' and means 'a pirate raid'. People who went off raiding in ships were said to be 'going Viking'.
While the term Viking is used in a general way to describe the people of Scandinavia during the medieval period, it's really a name for a profession -- it's like if we called all Spanish or French people Pirates. The Scandinavians were also explorers, farmers, fishermen and merchants -- not just Vikings. Indeed, the people who are usually referred to as Vikings were actually made up of several different groups, including the Danes, the Swedes and the Norwegians, who were themselves often broken into small petty kingdoms.
