My fil was just diagnosed with a 2:1 heart block. They’re installing a pacemaker. It appears to be a 3rd degree block. Can someone explain what this means? Everything online is geared to medical professionals and extremely hard to decipher.

A 2:1 is a second degree block. Another user described that. A third degree block is more dangerous and can be fatal. A pacemaker is installed to prevent a second degree block from progressing to a third degree block, which is where the top and bottom of the heart beat independently of one another.
