The document describes the development of the PulseGuard heart rate monitoring system created by a family to help manage their son Tom's severe epilepsy condition. Tom was diagnosed with Dravet syndrome at age 15, which causes frequent seizures and risks sudden unexplained death in epilepsy (SUDEP). PulseGuard is a wireless heart rate monitor that alerts caregivers to changes in heart rate that could indicate an ongoing seizure or other medical issue, allowing for early intervention. It has helped provide peace of mind for Tom's family by detecting his seizure activity whether he is at home or in residential care.
