Hi, Welcome to Health care magic forum.
Your husband is 88 years of age, and have atrial
fibrillation,
high cholesterol, pacemaker, and bad circulation in feet.
There is every possibility of having a
ischemia of the brain, by age and by circulation as well.
The other causes of the
dizziness may be due to the gastric irritation, infection of the internal ear,
hypertension, hypo tension, anemia,or
diabetes.
I advise you to consult a physician for diagnosis and treatment . He may prescribe him
ranitidine, and cinnerzine till the diagnosis is established.
Wishing for a quick and complete recovery.Thank you.
