But the burly belter, renowned for his theatrical, sweat-soaked shows, said the health scare has shaken his confidence.

“I’ve never really been nervous about going onstage, but I’m a little bit nervous,” Meat Loaf told reporters in London. “I’m having a few anxiety attacks.

“I just have to talk myself into being a bit calmer when I take the stage.”

The 52-year-old singer collapsed during a show at London’s Wembley Arena Nov. 17 and was taken to a hospital with a suspected heart attack. He was diagnosed with Wolff-Parkinson-White syndrome, which causes an irregular heartbeat and can lead to dizziness and fainting.

He had a catheter ablation, a procedure in which tissue is removed to restore a normal heartbeat, in London on Nov. 21.

The musician, famous for epic power ballads such as “Bat Out of Hell” and “I Would Do Anything for Love (But I Won’t Do That),” said he experienced dizzy spells all summer but hadn’t seen a doctor.

“I just chalked it up to being old,” said Meat Loaf, whose real name is Marvin Lee Aday.

The singer said the episode had been “pretty scary,” but that the treatment he’d received when he was rushed to the state-run Northwick Park Hospital had been “spectacular.”

Meat Loaf had said he hoped to resume his tour Sunday in Manchester, but his record company later said he’d been advised to have a few more days’ rest. He now hopes to perform Tuesday in Dublin, followed by dates in other cities.

“I’ve literally been in bed for almost two and a half weeks now, pretty much not doing a thing, so I’m not in show shape,” Meat Loaf said.

The singer said he’d play Wembley again in January, so that fans who’d attended the shortened show would have the chance to see the full performance.

Meat Loaf first gained fame with the 1977 album Bat Out of Hell, which has sold more than 30 million copies. He also has appeared in films including The Rocky Horror Picture Show and Fight Club.
