In 2022, aged just 20, Siobhan Wren was studying in the USA when her life suddenly changed. One afternoon, Siobhan was shopping with two friends when she suddenly collapsed on the pavement.
Having assumed she had fainted, her friends quickly managed to flag down a passing police car. The police officer was able to wake Siobhan, but she quickly lost consciousness again. They soon realised that she was in cardiac arrest. He immediately called for back-up and began CPR. Siobhan’s heart did not restart at the scene, or in the ambulance when she was treated with a defibrillator. More than 35 minutes after her cardiac arrest, her heart eventually restarted in hospital while she was on life support. She was later being fitted with an implantable cardioverter defibrillator (ICD) and discharged after five days.
Three months later, after returning to England, Siobhan experienced another frightening moment when her ICD delivered a shock after she ran up the stairs too quickly at home. She was taken to London’s Barts Hospital and stayed overnight before being discharged the following morning with a low-dose beta blocker. But Siobhan and her family were given little support or information about what had happened or what might happen next.
