Heartsine was founded in 1998 by John Anderson with a group of investors to further the development of portable cardiac defibrillators.
In the 1960s, Professor Anderson was approached to start the biomedical engineering group at the Royal Victoria Hospital and headed the effort to produce the world’s first mobile defibrillator to bring the expertise of the hospital to the patient to improve outcomes.
