Campaigners are calling for new laws to be included in this week's King's Speech that could see devices installed in cars across the country.
Research shows that 74 per cent of people believe that Automated External Defibrillators (AEDs) should be mandated inside all new cars sold in the UK.
The JumpStart health campaign has called on the Government to introduce new changes that would mandate the devices in new vehicles to crack down on soaring cardiac arrest rates.
Estimates show that more than 40,000 people across the UK suffer from out-of-hospital cardiac events every year.

The survival rate of these instances is just one in 10, while early defibrillation can improve survival rates by up to 70 per cent when used within three to five minutes.
With three-quarters of British people supporting the proposals, JumpStart is hoping to further boost awareness of the issue.
The campaign, which is funded by philanthropist Jonathan Harris CBE, has engaged with key stakeholders over the last nine months.
This includes the Department for Transport, the Department of Health and Social Care, and 10 Downing Street, with Parliamentarians from across both Houses supporting the measures.

Proposals put forward by JumpStart would also incorporate the maintenance of defibrillators into the existing MOT test framework.
If all new vehicles sold were to be fitted with a defibrillator, the UK would quickly develop one of the largest networks of AEDs in the world.
Jon McLeod, campaign director of JumpStart, said: "With Parliament now prorogued and the King's Speech just days away, this is the moment for the Government to act. Our proposal is simple, practical, and backed by three-quarters of the British public.
"Mandating defibrillators in new vehicles would turn the UK's car fleet into a life-saving public health resource, putting a defibrillator within reach in communities across the country, around the clock.
