Publius has it right, I'm afraid. Pink Floyd was still in the processing stage for this album when they found a newspaper headline that stated a woman got a pacemaker for her heart that was powered by atomic energy so she could survive childbirth. Hence the term ATOM HEART MOTHER. It's as simple as that. No shrooms, no hallucinagens, just a newspaper clipping.
