Henrik Lundqvist answered all the questions about another overtime loss, then sat at his stall for a long time alone with his thoughts, his skates still on.

He blamed himself for not being able to stop Brad Marchand’s winner at 15:40 of overtime as the Bruins won Game 1 of this Eastern Conference semifinal series, 3-2, Thursday night at TD Garden.

He blamed himself even though Patrice Bergeron found Marchand, who had beaten Mats Zuccarello up ice, skating freely to the crease on a 3-on-2.

But there were limits. Lundqvist, who made 45 saves, including 15 in overtime as the Rangers were outshot, 16-5, does not believe the Rangers’ incongruous 3-11 overtime record with him in net solely reflects on him.

“I’ve got to be really careful to ask myself the right question there,” said Lundqvist, who earlier in the game had his shutout streak of 152:23 snapped. “Have I played bad in overtime? No. Can I score? No. Is it frustrating? Yes. My record is terrible in overtime, but I’ve just got to stick with it, play my game.”

Game 2 is Sunday at 3 p.m. at TD Garden before the series shifts to Madison Square Garden for Game 3 on Tuesday night.

The Bruins’ overtime onslaught started when they took six power-play shots after Derek Dorsett interfered with Rich Peverley at 2:20.

“In overtime, we had a couple of chances, I had one,” Rangers defenseman Anton Stralman said. “They had 100, probably. We couldn’t get any pressure on them at all. They were on top of us. It was tough.”
