it all came to a head last friday, when my heart started racing while i was driving. I drove straight to the drs in a state of panic convinced i only had hours to live. He took my blood pressure which was up and had put me on 25mg a day of Atenolol (which i'm now convinced will kill me). Had lots of bloods test, which have come back normal and this friday i have an ecg. Anyway about 3 oclock this morning i woke with a pain in my chest that when through to my back, i felt sweaty and slighting dizzy, i then convinced myself i was haveing a heart attack. I'm so sure that these tablets are doing me more harm than good as my blood pressure is usually ok at home. I do understand that Atenolol is used for BP, Anxiety & to slow your heart rate down. I'm in such a mess and everyone is getting fed up with me, i don't know what to do. Please help.
