many circumstances can lead to seizures i comatose patients depending on the cause of the coma. In this case with a past history of myocardial infarction
, this is a risk factor for formation of clots or emboli. These could move to the brain, cause focal neurologic manifestations
in affected areas like stroke. Secondly, in comatose patients, high temperatures , low blood glucose
could easily lead to seizures. Electrolyte abnormalities in these comatose patients too could lead to these seizures. Reason why in these patients, a keen supervision of body temperature, blood glucose and electrolyte levels, electrolyte disturbances many times a day are usually done.
Depending on the frequency of these seizures, this could lead to permanent brain damage
. The more frequent they are, the greater the risk of having permanent brain damage, reason why monitoring and prompt treatment of the seizures is important.
Thanks and best regards as I hope this helps,
