Introduction: A global pandemic of Coronavirus (COVID-19) disease was developed in 2019, primarily affecting respiratory tract and causing asymptomatic subclinical infections up to severe acute respiratory distress syndrome that need hospital admittance to coronary care units (CCUs) and intensive care unit (ICU) where nursing care is required. Acute myocardial injury and arrhythmia may also occur, potentially contributing to inclusive illness and death in COVID-19 patients. Left bundle branch block (LBBB) is tropical illness that may happen in COVID-19 patients. Aim of the work: To investigate the effect of LBBB on quick-term death probability in patients with COVID-19. Materials and Methods: Retrospective study on the incidence of LBBB in patients with COVID-19 in Tobruk city. Study included both male and female samples, including all patients with LBBB (aged 37-82 years) those managed in CCU and ICU. Patients' records were collected from Tobruk Medical Center inpatients – 42 total cases from January 1, 2020 to December 31, 2021. All necessary basic information and data were obtained from medical records. Excel was used for data assortment and expressive study. Results: Our scientific work included 42 patients. Of these, 31 (74%) were male and 11 (26%) were female. Male gender is predominant on female gender as ratio 2.8:1. Patients' ages included at this work oscillated between 37 and 82 years (mean age; 59.5 years). The highest age group observed to have great pervasiveness of LBBB in COVID-19 patients was 50-59 years (38.1%). Conclusion: Left bundle branch block is taken into consideration to be the primary symptom in sufferers with COVID-19 infection. In addition, studies are wanted to explain the real mechanism and suitable treatment.
