Abstract

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is known to be associated with myocardial injury. Electrocardiographic (ECG) abnormalities could be a useful tool to identify the various forms of cardiac manifestations of SARS- CoV-2 infection. The aim of our study was to assess specific ECG patterns in COVID-19 patients admitted in New Covid ICU of KIMS Hubballi which could be related to in-hospital mortality. Cardiac involvement in patients with SARS-CoV-2 requires change in management as well carries poor prognostication. Methods: We retrospectively analyzed the 12-lead ECG of 100 patients hospitalized in New Covid ICU of Karnataka Institute of Medical Sciences, Hubballi for respiratory distress in from 1StFebruary 2021 to May 31 2021(Second wave) who were diagnosed with covid-19 after naso-pharyngeal swab. Basic demographic data like name, age, sex co-morbities of patients were recorded. 12 lead ECG with normal standardization (speed of 25 mm/s and a voltage of 10 mm/mV) was taken for all study patients and following ECG features like rate, rhythm, axis abnormalities of p, QRS t waves, QTc interval were analyzed in each patient. This is an Observational non-randomized study. Results: Among 100 patients included in the study, most common electrocardiographic feature was sinus tachycardia (n=48), ST elevation Myocardial infarction was observed in three patients (n=3), atrial fibrillation in 2 patients (n=2), one patient had svt (n=1), complete heart block in two patients (n=2) and S1Q3T3 was observed in three patients (n=3). Average QTc was 414msec, with maximum QTc observed was 566msec. Conclusion: Cardiac manifestations play significant part in the treatment and overall prognosis of SARS-CoV-2 patients. Electrocardiography, a simple affordable tool helps in identifying such cardiac manifestations, hence aids in the management of patients
