FIGURE 3.

Reference indices for the use of echocardiography in COVID‐19 patients in different possible clinical scenarios. McConnell's sign = echocardiographic evidence of depressed contractility of RV free wall compared to RV apex. AcT = right ventricular outflow Doppler acceleration time; AMI = acute myocardial infarction; EDV = end‐diastolic volume; EF = ejection fraction; ESV = end‐systolic volume; GCS = global circumferential strain; GLS = global longitudinal strain; fwRVLS = free wall right ventricular longitudinal strain; HF = heart failure; IVS = interventricular septum; LA = left atrium; LV = left ventricle; PPE = personal protective equipment; RA = right atrium; RV = right ventricle; RVFAC = right ventricular fractional area change; SI = sphericity index; TAPSE = tricuspid annular plane systolic excursion; TRPG = tricuspid regurgitant pulmonary gradient; WMA = wall‐motion abnormalities
