What do you think?

All sin leads to death. It is only forgiven sin through the shed blood of Christ Jesus that escapes death (Hell). Since the 1 John verses are just after the verse on assurance (1 John 5:13) he cannot be thinking of a 'falling away', so I wouldn't link it with the Hebrews passage.

As to whether it is the same as the 'unpardonable sin' I cannot say for sure, but they would be very similar.
