Hello from Buenos Aires, Argentina. So immensely grateful for all the wonderful people and information here. Been lurking since I was diagnosed as in chronic afib (on EKG), mid March by a cardiologist. I consulted because stairs suddenly became an issue. Mid May with lab and echocardiogram results I continued in afib (EKG). Cardiologist prescribed anticoagulants and Bisoprolol (5 mg) to try. Sheby Ginny51 - AFIBBERS FORUM
