Lundqvist preserved the win when he made a back door save against Justin Williams with 1:37 remaining.
"I had to improvise a little bit," said Lundqvist, who is 30-12-1 all-time against Carolina. "I was caught. I didn't feel like I had time to get a good push, so I kind of went down, then up with the blocker. It worked."
Williams had a game-high 10 shots on goal.
"I just tried to catch it and get it up high," Williams said. "I think a defenseman got a stick on it, but [Lundqvist] was right there and I wasn't able to get to the rebound on it. We certainly had a lot of chances to win."
