Sponsor's own description
In patients with coronavirus disease (COVID-19), severe dyspnea is the most dramatic complication.Severe respiratory difficulties may include electrocardiographic frontal QRS axis rightward shift (Rws) and clockwise rotation (Cwr). This study investigated the predictability of advanced lung tomography findings with QRS axis shift and rotation. This was a retrospective analysis of 160 patients.The patients were divided into two groups: normal oxygen saturation(SpO2) (NS; n = 80) and low SpO2(LS;n = 80).They were then divided into NS Rws (n = 37), NS leftward shift (Lws; n = 43), LS Rws (n = 40), and LS Lws (n = 40) according to electrocardiographic follow-up findings. These groups were compared in terms of electrocardiographic rotation (Cwr, counterclockwise rotation, or normal transition), tomographic stage (CO-RADS5(advanced)/CO-RADS1-4), electrocardiographic intervals, and laboratory findings
