Bruising ultimately affected head and pulse (5-4,4)

I believe the answer is:
black-eyed bean
'bruising ultimately affected head and pulse' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.
'bruising ultimately affected head and pulse' is the wordplay.
'bruising' becomes 'black eye' (I have seen 'Facial bruising ' mean 'black eye' so perhaps 'bruising' could also mean 'black eye').
'ultimately affected head' becomes 'd' (I can't justify this - if you can you should believe this answer much more).
'and' says to put letters next to each other.
'pulse' becomes 'bean' (beans are a type of pulse).
'blackeye'+'d'+'bean'='BLACK-EYED BEAN'
Can you help me to learn more?
