Electrical damage symptoms and conditions

Changed from Atenolol to Lisinoprol because of the new guidelines about beta blockers versus ACE inhibitors. Within 24 hours I was dizzy, weak, pains in my abdomen, tight chest, heart pounding, breathless, could not run for the bus. I persevered and took 3 doses (5 mgs each) but eventually felt so bad I stopped and after 24 hours went back on Atenolo. Within 1 hour I was much improved. In spite of the guidelines and the long term dangers of beta blockers, I feel I have no choice but to stick with them as my quality of life on Lininopril was unacceptable.
