The Hurricanes tied the best-of-7 series 1-1 after losing Game 1, 5-4, on Tuesday, when they had an early two-goal lead, couldn't hold it, came back twice to tie it and eventually lost late in regulation.
Game 3 is at T-Mobile Arena in Las Vegas on Saturday (8 p.m. ET; ABC, SN, TVAS, CBC).
"This is exciting," Jarvis said. "This is what playoff hockey is all about; tight games and momentum swings and you never really know what's going to happen next. I don't think you can ask any more of a playoff series."
Logan Stankoven, Mark Jankowski and Jordan Staal scored in the third period to erase a 2-0 deficit and give Carolina a short-lived 3-2 lead before Mark Stone tied it at 18:39. Gostisbehere had two assists. Frederik Andersen made 23 saves.
Carolina improved to 6-0 in overtime games in the Stanley Cup Playoffs. Vegas dropped to 3-1.
The Hurricanes were 2-for-4 on the power play with Staal and Jarvis getting it going after looking lethargic on it in Game 1 (0-for-2, no shots) and the first period of Game 2 (0-for-2, one shot). They were also 4-for-4 on the penalty kill, improving to 7-for-7 in the series.
"Our group, this playoffs especially, has just been holding the rope, like we've been talking about," Staal said. "Just staying with it, just staying with it, and just being patient with our game and trusting our game. I think we've done a great job of that."
