The surface electrocardiogram is the first line assessment of cardiac electrical system. We aimed to interpret classically the electrocardiographic parameters at admission and during hospital course and association of them with prognosis in patients admitted with diagnosis of infection with SARS-CoV-2. </span><br> <span style="line-height:14pt"><b><i><span style="color:blue">Methods:</span></i></b> Surface electrocardiograms (ECG) were obtained from 180 patients with SARS-CoV-2 infection at a large tertiary referral university hospital at north of Iran in Babol. The electrocardiographic waves, intervals and segments in addition to supraventricular and ventricular arrhythmias were depicted. Our cohort included two groups: discharged alive and dead during the hospital course. We compared the ECG characteristics of patients who died vs. survived ones. </span><br> <span style="line-height:14pt"><b><i><span style="color:blue">Results:</span></i></b> Some ECG parameters of 180 hospitalized patients were significantly associated with mortality, like heart rate (p< 0.001), bundle branch block (P= 0.035), fragmented QRS (P= 0.015), ST elevation (P= 0.004), T p-e duration (P= 0.006), premature atrial and ventricular complexes (P= 0.030, P= 0.004) and atrial fibrillation (P= 0.003). </span><br> <span style="line-height:14pt"><b><i><span style="color:blue">Conclusion</span></i></b><i><span style="color:blue">:</span></i> The SARS-CoV-2 infection had several impacts on cardiac electrical system which may monitored with a simple and easily accessible tool like ECG. This tool also helpful in the risk stratification of patients.</span></span></span><br> &nbsp; Electrocardiogram, SARS-CoV-2 infection, Mortality 444 450 http://caspjim.com/browse.php?a_code=A-10-139-5&slc_lang=en&sid=1 Samaneh Karbalaie esmaeilzad Drkarbalaie62@yahoo.com 100319475328460048929 100319475328460048929 No Department of Cardiology, School of Medicine, Babol University of Medical sciences, Babol, Iran Mohammad taghi Hedayati drmohammad.hedayati@yahoo.com 100319475328460048930 100319475328460048930 No Clinical research development Unit of Rouhani Hospital, Babol University of Medical sciences, Babol, Iran Naghmeh Ziaie Ziaiexn@yahoo.com 100319475328460048931 100319475328460048931 No Clinical research development Unit of Rouhani Hospital, Babol University of Medical sciences, Babol, Iran.
