Cardiacs are an English rock band formed in 1977, originally as Cardiac Arrest, led by Tim Smith. Noted for their complex, varied and intense compositional style and for their eccentric, theatrical stage shows, they have been hailed as an influence by bands as diverse as Blur, Faith No More and Radiohead.

Cardiacs have released eight studio albums plus a number of live albums, compilation albums and singles between 1980 and 2007, and are best known for the 1988 minor hit single "Is This the Life?" They are also noted for attracting strongly diverse responses: they have remained one of Britain's leading cult rock bands during their four-decade-spanning career, but have also attracted virulent critical attack (including a lengthy editorial ban from the British music magazine New Musical Express).
