INITIAL ELECTROCARDIOGRAPHIC PROFILE OF THE POPULATION OF TANGIERS – MOROCCO INFECTED WITH SARS CoV2: ABOUT 1087 CASES

Abstract

Abstract Introduction Coronavirus disease 2019 (COVID-19) is a pathology which initially affects the respiratory system, but also many other noble organs due to his inflammatory phase (Cytokine Storm), especially the cardiovascular system. The cardiovascular risk factors present in a population infected with SARS-COV 2 are of particular interest. The ECG is a fast available means to get an idea about the cardiac status. This permits not only to diagnose an unknown pre-existing pathology but also to detect a killing cardiac complication of the SARS COV-2 infection. Methods We performed a cross-sectional study on COVID-19 patients passing through Tangiers sorting center. Clinical characteristics and ECG variables were manually abstracted from the electronic health record and first ECG. Our aim was to describe the electrocardiographic features of Covid-19 Patients in Morocco. Results 1087 patients who presented to the COVID 19 triage center in Tangier-Morocco were systematically given a pre-treatment ECG before deciding on the type of management: outpatient, ward, intensive care.The mean age was 42.78 years, 30.5% of the cases had at least one cardiovascular risk factor, 8.6% of the patients were followed for hypertension, 8.2% for type 1 or 2 diabetes, 10.9% of the patients were obese with a BMI greater than 30, and 26.4% of the patients were either men over 50 or women over 60. The mean heart rate was 80.89 bpm ± 15.58; The mean PR interval was 149.51 ± 21.70; The mean QRS duration was 98.59 ms ± 11.71; The mean QTc interval was 406.62 ms ± 24.32. We found: A conduction disorder in 11.1% of patients, 1.6% of 1st degree BAV, 2 of incomplete right bundle branch block, 5.7% of complete BBD, 0.9% of BBG and 1.4% of left anterior hemiblock. A rhythm disorder in 5.1% of our patients, 2.1% of ventricular extrasystole, 1.6% of supraventricular extrasystole, 1.1% of atrial fibrillation, wolf- parkinson-white syndrome in 0.3% of patients and 0.5% of Brugada pattern. A repolarization disorder in 5.2% of our population. 3.6% of patients had negative T waves and 1.6% had ST segment abnormalities. We also found a significant association between the presence of cardiovascular risk factors and electrical abnormality. Conclusion We found that the majority of EKG were normal and all critically ill patients had a large spectrum of EKG abnormalities. Pending the results, we still believe that we can potentially establish a severity score including EKG to predict inpatient mortality in Moroccan covid-19 patients.
