Sefton Central Labour MP Bill Esterson has given his backing to a campaign to get defibrillators installed at all schools.
Bill met with campaigners who want to see the life-saving equipment installed in every public building.
A campaign group was set up following the death of 12-year-old Liverpool schoolboy Oliver King.
Oliver died of Sudden Arrhythmic Death Syndrome (SADS) while swimming in his school pool.
SADS affects young people aged between 12 and 35. It claims the lives of 12 young people each week.
Members of the Oliver King Foundation met with Bill to discuss their campaign.
Speaking afterwards Bill said: "It is shocking how many young people are losing their lives week in week out because of this condition.
"Many of these deaths could be prevented by having easy access to defibrillators. This was something which we saw when Bolton's Fabrice Muambar collapsed on the pitch due to suffering from a heart condition. His life was saved because paramedics were on the pitch within minutes with defibrillators.
"This just shows what can be done and how a young life can be saved."
Bill thanked the campaigners for travelling to London to speak to him and other Labour MPs about the issue.
Bill said: "This campaign is raising awareness about a condition which is claiming far too many young lives.
"I was only too pleased to meet with them in Parliament and I give them my full support. I hope that as many people as possible in Sefton Central also give their backing to this life-saving campaign.
"It's easy to add your name to the campaign, just sign the e-petition on the government website to urge this government to introduce defibrillators to all public buildings by 2017 and to also offer all people aged between 12 and 35 a simple ECG test, which could reduce the current death rate of 12 young people a week.
"These are simple steps, but they are steps which could reduce the number of young people dying from this condition each year."
