Was doing fine with no prescription meds until last year when I began irregularly spiking a high blood pressure. Have been on amlodipine 5mg since December 14 and have recently developed an consistent irregular heart beat (frequent triple beats - have longtime history of infrequent triple beats.) EKG last Friday OK . Instead of switching me to another medication, MD prescribed Coreg which seems to be contraindicated for me; I m not in heart failure nor is my ejection rate 4O or less; recent stress test ejection rate was 66% - down from 90% 3 years ago. I had a silent heart attack in fall of 08, stent January 09. Have left bundle block, allergies to ibuprofen (angioedema), sulfa, injectable iodides and other substances. History of CFIDS, Polymyalgia Rheumatica, food intolerances. Also history of NAFLD, cysts on both kidneys, kidney stone right kidney. Are there any blood pressure medications that would be better suited than Coreg? (B.D. 7/26/32, Ht 5 2 , Wt 148).
