<![CDATA[Abstract: We reported a 77-year old female, admitted to the Prof dr RD Kandou General Hospital due to dyspnea. Physical examination revealed hypertension, rales and wheezing in both lungs, heart enlargement, and an auscultation heart rate of 140 beats per minute. ECG showed a rapid response atrial fibrillation. Besides that, chest X ray examination showed cardiomegaly with CTR>50%. A working diagnosis revealed lung edema (pneumonia as a differential diagnosis),  and functional heart failure class II-III due to hypertensive heart disease, associated with a rapid response atrial fibrillation. Bisoprolol 5 mg once daily was given immediately along with oxygen, a NaCL 0.9% infusion, and furosemide 40 mg intravenously. In addition to this, was added ceftriaxon 1g twice daily, captopril 6.25 mg three times daily, furosemide 40mg, thiazide 25 mg, and aspirin 80 mg once daily, coenzyme Q10 100 mg twice daily, and trimetazidine 35 mg two tablets daily. The ECG result after approximately 10 hours  was a normal respone atrial fibrillation. The patient left the hospital at the fifth day with the same ECG result. Key words: atrial fibrillation, bisoprolol, congestive heart failure. Abstrak: Telah dilaporkan seorang perempuan berusia 77 tahun, dirawat di RSU Prof dr RD Kandou dengan keluhan sesak napas.
