Woman saves partner after he suffers cardiac arrest in his sleep

Sophie Bettles saved her partner, Jack Dennis, in Underwood, Nottinghamshire, after he suffered a cardiac arrest while sleeping.

Bettles noticed unusual noises and realized Jack was not breathing. She contacted emergency services and followed the instructions of a call handler to perform cardiopulmonary resuscitation (CPR) for 20 minutes before paramedics arrived. Medical staff later confirmed that Dennis had an undiagnosed congenital heart defect. He underwent major surgery to replace his aortic valve and part of his aorta.

Dennis returned to his job as a plant engineer in August. Paramedics noted that Bettles had already successfully restarted Dennis's heart before they reached the bedroom. During his treatment, Dennis suffered a second cardiac arrest which required paramedics to use a defibrillator to deliver nine shocks to his chest.
