"I'm required to wear these monitors to see what my heart is doing throughout the day," he explained. "I feel like a robot from WESTWORLD."

"Thank you all for your kindness," he continued. "You have no idea how much it helps."

Harper originally announced the news via social media with a photo snapped from his hospital bed, which also featured his beloved dog, "nurse" Karl, by his side.

"Well I guess you all heard what happened. Two weeks ago yesterday I had a heart attack," he revealed. "I am feeling better. Just taking it easy."

"KARL has been a great nurse," he added. "I want to thank everyone for the outpouring of messages and support. It feels good to be cared about. I've been home for 8 days now. Again, THANK YOU SO MUCH!! I'm lucky to have such good friends and family to take care of me right now."
