In December 2013, Tebbit suffered from a heart scare, praising the NHS for their quick and decisive action. In a May 2014 interview, he talked about discovering he had been suffering with a form of cardiac arrhythmia for more than 40 years: "The suspicion I had a heart problem caused me to puzzle over earlier incidents in my life," he said, reflecting on his RAF jet fighter crash in 1954. "I suspect that, that morning, stressed from the previous day and having had little sleep, I lost consciousness on that take-off run."
