and shortness of breath for the last month. During this period, she
experienced shortness of breath when engaged in routine activities,
chest discomfort and fatigue. She did not mention any symptoms of cough,
nausea, vomiting, diarrhea and fever, and no direct contact with a
coronavirus-infected person. Additionally, in the last two weeks, she
went to a hospital in her city of residence and echocardiography was
conducted for her which, according to her, did not have any remarkable
findings. However, after two weeks, not only the symptoms did not
improve, but they deteriorated. She presented to our hospital for more
investigations. She had no history of previous surgery or
hospitalization, though she was on Losartan for controlling her chronic
hypertension since five months ago. In primary examinations, heart and
lung auscultation were normal and the vital signs included respiratory
