Did Paul Daneman, Have A Heart Attack Whilst Playing The Part Of Someone Who Had A Heart Attack?

In the year 1983, while Daneman was in the middle of rehearsals for an upcoming West End theatre production, he suffered a hearth attack. Till date, this is considered one of the most bizarre incidents in entertainment, since, Daneman at the time was actually rehearsing for the part of a character who, in the script suffers a heart attack.
Medics advised him, to take ample of rest and time off after his cardiac arrest. It was during this time that Daneman penned down the script for his television comedy 'Affairs of the Heart'. Incidentally, the story surrounding Daneman's lead character was his own-that of a recovering heart patient and his family life. However, once the sitcom aired in 1985, it didn't meet with much success.
