I had palpations--finally a surge in b/p to + 200 over +100
was in the ER twice & one ER doctor mentioned it could be the HCTZ
I have been OFF the HCTZ ---look up the side effects for that and see it it relates to your problem if you have one.
I have 20 mg of lisinopril now up from 12.5 before.
4 days and everything is swell. No palpatations--back on exercise routine.
Good Luck everyone
