A Bronx woman was charged with attempted murder for allegedly shooting her husband in the head and leaving him clinging to life, cops said.

Johanna Pagan-Alomar, 52, allegedly shot her 53-year-old hubby inside their home on Grand Avenue near West 176 Street in Morris Heights around 7:10 a.m. Tuesday, police said.

He was rushed to St. Barnabas Hospital, where he was listed in critical condition, cops and law enforcement sources said. 

Pagan-Alomar was arrested early Wednesday and charged with attempted murder, assault and criminal possession of a weapon, authorities said. 

The couple did not have a prior domestic violence history, and Pagan-Alomar claimed “self defense,” the sources said. 

Pagan-Alomar has been arrested four times in the past, but none of them are domestic offenses, cops said.
