TV entrepreneur Duncan Bannatyne has returned home after being discharged from hospital.
Tests have confirmed that he did not suffer a heart attack in a health scare which saw him rushed to a hospital in Darlington, a company spokesman has said.
The 63-year-old Dragons' Den star fell ill while at the headquarters of his gym business in Darlington and was taken by ambulance to the town's Memorial Hospital on Monday.
A Bannatyne Group spokesman said: "Everyone at the company is relieved that tests have confirmed Duncan's health scare was not a heart attack.
"He is now to spend a few days recuperating from his chest pains away from the stresses of his busy life.
"He has asked us to thank the many hundreds of people who have contacted him to express their good wishes and support and to thank the dedicated staff at Darlington Memorial Hospital for the kindness and care."
He was well enough on Tuesday morning to tell his 540,000-plus followers on Twitter: "Just waiting for Doctors rounds but am sure I will get all clear to go home soon."
