McCool: "It was your heart."

American retired professional wrestler Mark William Calaway, aka 'The Undertaker', is presented prior to the Riyadh Season Cup Final match between Al Hilal and Al-Nassr at Kingdom Arena on February 08, 2024 ,in Riyadh, Saudi Arabia. MoreMcCool continued, "You weren't supposed to go anywhere. You didn't want me to tell anybody. Not fair to me, not fair. We were in the hospital for four nights two weeks before WrestleMania. Yeah, you weren't supposed to go. I'm not mad at it because I'd probably be the same [way], but it was terrifying. I couldn't focus on anything else.

"I did. That I had scheduled in January, that's crazy about it. You went to the doctor March 28th, I'll never forget. Then you called me and you were like, 'They won't run the heart exam.' Just a routine heart scan that we were going to do."McCool: "Got you into another [appointment] about an hour later. They had one appointment open. Come to find out, you had been in chronic AFib for who knows how long. But the scary part was that you didn't feel any symptoms, so we didn't know.
Yeah, you came in a few times out of breath and I'd give you a hard time like, 'Dude, you were just throwing the ball with the dog, why are you so out of breath?' Or going up the stairs to pray with the kids, 'Why are you out of breath', not thinking it was an actual heart issue. So, yeah. Medicines didn't work and we ended up in the ER on a Friday. Of course you wouldn't stay the night."
"At the end of Kai's flag football all day Saturday, you looked at me and said, 'I'm still in AFib,' because you were doing it with the watch. I was like, 'If you're not out of AFib when we're getting ready to go to church tomorrow morning, we're going to the hospital.' Thankfully you agreed."
Hospitalization and Recovery
"We went to the hospital, numbers were out of whack. Heartbeat was out of whack. Your ejection fraction of how the blood was pumping was 30%, it wasn't much. Supposed to be 100%, obviously. We ended up staying in the hospital for four nights where they actually had to cardiovert you and shock you back to a normal rhythm. That sadly lasted, what, 24 hours. Maybe 48. After four days we go home, two days later you're back in AFib. Man I was stressed."
The couple confirmed that The Undertaker's heart issues have since been resolved.
