A heavy goods vehicle driver from Hemel Hempstead died after suffering heart failure whilst engaged in sexual intercourse, an inquest has heard.
Coroner Edward Thomas heard that Paul Swendell, of The Sonnets, was found lying on his back in bed, completely unresponsive, by paramedics.
The 55 year-old was taken to Hemel Hempstead Hospital where doctors were unable to resuscitate him.
Mr Thomas, quoting from the testimony of the registrar on duty at the time, said: "Mr Swendell was engaged in sexual intercourse when he became unresponsive."
The inquest heard that Mr Swendell had an asymptomatic heart disease, which meant there were no external symptoms and so the problem could not have been detected beforehand.
Mr Swendell, who was a smoker but rarely touched alcohol, last saw his GP on May 10, 2007. His GP Dr Fernandes said: "His blood pressure was normal, but he complained of heartburn when he ate and other stress."
He was admitted to hospital the day before he died when he collapsed suddenly at work, but was discharged after doctors examined him and found no traces of illness.
Mr Thomas said: "He died of cardiac failure after suffering cardiac dysrhythmia. He died of natural causes."
