Bella Montoya, 76, was first declared dead by a doctor at a hospital in the city of Babahoyo last week.
But when mourners attending her wake heard her knocking on her coffin, she was immediately rushed back to the same hospital for treatment.
After seven days in intensive care, Ecuador's health ministry confirmed she died on Friday from an ischemic stroke.
The ministry's statement added that she had remained under "permanent surveillance" while at the hospital.
