My 45 year old husband blacked out at the wheel of car 5/9. On 5/10 the cardiologists put in a pacemaker because his heart kept stopping. Prior to this, symptoms his doctor ignored were: sudden onset of heartburn; fatigue; leg cramps; achiness; could not work out at gym anymore (from 4-5 days per week prior). Doctor prescribed (without a stress test that we requested because of high concerns of health, but doc did not want to be told what tests were needed), prescribed him Celexa for fatigue, nexium for heartburn and doxazosin for frequent bladder. He was told that one or two of the doxazosin as needed per day. He took two on 5/8 for the first time, but no one gave us info on the drug. Now he has a pacemaker, they also did TEE test and discovered a leaking valve (aortic insufficiency), a positive tilt test showed neurocardiogenic syncope for which the cardiologist has prescribed Toprol XL. My research shows that this drug should not be taken if slow heartrate is a problem, which his is. His resting heart rate is 55 or so, lower in sleep, about 45, so the pacemaker kicks in at 50. Why then, Toprol? I'm losing faith in docs, so please provide some advice. Thanks! side note, he also has had a heart cath, no blockages, but something about the aorta being extended? The doctor suggests that his weightlifting may have caused this, but he used to lift only 285 once in a while, mostly cardio workouts with weights. He's 6'1", 215 pounds, very strong upper body. Would the doxazosin have had something to do with the heart damage and disease now?
