A heart screening event for young people is being held in memory of a 15-year-old girl.
Madeline Siddall, of Eckington, in Derbyshire, died from sudden cardiac arrest in 2011 after she collapsed at her boyfriend’s house.
The fully-booked event in Warsop, Nottinghamshire, will give 100 people a electrocardiogram (ECG) on Saturday.
Her mother Anne, who raised funds for the event, said she hoped it would stop others enduring what her family did.
Mrs Siddally, 54, said about three or four years after Madeline’s death she decided she wanted to create a legacy for her and started fundraising for the charity Cardiac Risk in the Young (CRY).
This has been used to finance Saturday’s screening event – costing £6,000 – as well as two previous ones.
CRY said every week in the UK about 12 people aged under 35 die suddenly from a previously undiagnosed heart condition.
The previous screenings found two or three young people who needed further investigation, said Mrs Siddall.
“It is a life sentence losing a child. It is massively important that children are screened,” she said.
“It might prevent someone else going through what we went through.”
