The 30-year-old, who won cycling and athletics gold at the Rio Games, knew she had to beat the time of 35.830 seconds set by Canadian world champion Kate O'Brien to win Britain's seventh gold of the Games
And she smashed that with a brilliant 34.812secs - beating the old record by 0.411secs.
"I tried not to cry on the podium, I tried to enjoy this moment," she told Channel 4.
"I did enjoy Rio but was trying to go well that I didn't really, it's a bit overwhelming."
Earlier, Britain's Jaco van Gass claimed his second medal of the Games with bronze in the C1-3 1000m time trial.
The pursuit gold medallist set a new world record in his C3 category, but it wasn't enough for victory.
There were also bronzes on day three for sprinter Maria Lyle in the opening session of the athletics competition and for powerlifting debutant Olivia Broome.
Lyle finished third in the T35 100m as China's Xia Zhou set a new world record while Broome had a best lift of 107kg in the -50kg event.
Broome's team-mate Ali Jawad finished sixth in the men's -59kg event after a build-up where his training was not only affected by Covid but also by the Crohn's disease which he deals with on a daily basis.
