"My heart was going wild at a funny rhythm. It was probably only about four degrees, really cold, and I got inside. Sweat from me is hitting the ground hard so I knew I wasn't right," he said of the match against Cambridge University.
"That's when I thought I was going to die."
Taylor, 26, thought he was suffering from a viral infection but scans showed he had a heart condition known as Arrhythmogenic Right Ventricular Arrhythmia (ARVC), the same condition that almost killed former Bolton Wanderers footballer Fabrice Muamba.
The middle-order batsman played seven tests and 27 one-day internationals for England and captained the side against Ireland in May last year.
