Speaking outside the couple's home in south-west London, make-up artist Barbara Robbin said she had no idea what caused 56-year-old husband's death.
"We don't know yet what happened," she told reporters. "He had a strong heart, so I don't think it was a heart attack. But we just don't know until the coroner's report.
"Maybe he had a fit, maybe it was his heart. We just don't know."
Police said the comedian's death is not believed to be suspicious.
On Monday a Scotland Yard spokesman said officers were called by London Ambulance Service to a house in Barnes, south-west London at around 1.20pm where "a man, aged in his 50s, was pronounced dead at the scene".
Meanwhile Mayall's Comic Strip Presents colleague Peter Richardson has told BBC Radio 4's Today Programme, the comedian and actor was happy and healthy in the hours before his death.
He said his son was one of the last people to see him alive.
Richardson, who directed Mayall in a series of TV shows, explained his son saw him around half an hour before he died at his London home.
He said: "He was happily chatting away and it was very quick and we still don't quite know what happened but it was a seizure of some sort."
Mayall shot to fame playing Rick in television series The Young Ones, alongside long-time collaborator and friend Adrian Edmondson, who he had met at Manchester University.
Mayall's career included appearances in popular television shows Blackadder, Bottom and The New Statesman.
He had also featured in a number of films including the 1991 hit Drop Dead Fred, and alongside Edmondson again in 1999 for Guest House Paradiso,
Paying tribute to his friend, Edmondson said: "There were times when Rik and I were writing together when we almost died laughing. They were some of the most carefree stupid days I ever had, and I feel privileged to have shared them with him.
"And now he's died for real. Without me. Selfish b*****d."
Mayall's daughter Bonnie has paid tribute to her father on Facebook calling him a 'generous, foul mouthed and hysterical father.'
She said: "My dad was loved not only by my family, but by many many others. We will never forget him and neither will the world.
"R.I.P to the man, the myth, the legend - my wonderful, generous, foul mouthed and hysterical father. My idol now and forever. We love you daddy."
Other stars of television and comedy have paid their respects, including impressionist Rory Bremner said: "Awful news about Rik Mayall - a fireball of creative comic energy and inspiration. Such brilliant raw talent."
Blackadder producer John Lloyd said Mayall was "just extraordinary".
He added: "It's really a dreadful piece of news. I remember going to the very first night of the Comedy Store and thinking 'Where does this come from?'
"It was the most extraordinary thing, him and Ade Edmondson doing the Dangerous Brothers, they were called, and you just felt you were in the presence of something, a whole revolutionary thing."
