en The Prevalence of Cardiac Arrhythmias in COVID-19 Patients Undergoing CRRT During the First 24 Hours of ICU Admission Infectious Disease Infectious Disease Original Research Original Research Background: This study aimed to determine the prevalence of cardiac arrhythmias in COVID-19 patients undergoing Continuous Renal Replacement Therapy (CRRT) during the first 24 hours of ICU admission.    Methods: This cross-sectional study was conducted to assess the prevalence of cardiac arrhythmias among 78 COVID-19 patients undergoing CRRT hemoperfusion during the first 24 hours of hospitalization in the ICU of Kowsar Hospital, Semnan, in 2020. Data were collected using a checklist that included demographic characteristics, underlying diseases, and types of cardiac arrhythmias, extracted from patients’ medical records in the hospital’s medical records department. Data analysis was performed using SPSS software, version 26.    Results: The mean (± SD) age of the patients was 54.68 ± 1.61 years. The proportions of males and females were 41% and 59%, respectively. The overall prevalence of cardiac arrhythmia was 21.8%, with bradycardia being the most common type (7.7%). The prevalence rates of heart disease, hypertension, diabetes, and hyperlipidemia were 48.7%, 39.7%, 28.2%, and 26.9%, respectively. Additionally, 20.5% of patients had a history of cardiovascular disease. No statistically significant associations were found between cardiac arrhythmia and age, gender, or underlying conditions such as heart disease, hypertension, diabetes, and hyperlipidemia (P>0.05). However, the prevalence of supraventricular arrhythmia (100%) and ventricular arrhythmia (66.7%) was significantly higher among patients with a history of cardiovascular disease (P<0.001).    Conclusion: Our study demonstrated a substantial prevalence of cardiac arrhythmia in COVID-19 patients undergoing CRRT within the first 24 hours of ICU admission. The findings emphasize the importance of recognizing this vulnerable period for arrhythmia development and highlight the need for proactive measures to mitigate risks in this high-risk population.   Cardiac Arrhythmias, COVID-19, CRRT hemoperfusion, ICU 58 63 http://mjiri.iums.ac.ir/browse.php?a_code=A-10-9433-1&slc_lang=en&sid=1 Samira Mehrabi Pari Samirameh200@gmail.com 200319475328460096298 200319475328460096298 No Clinical Research Development Unit, Kowsar Educational, Research and Therapeutic Hospital, Semnan University of Medical Sciences, Semnan, Iran Amir Hossein Yaghoubian Yaghoubian_amir02@gmail.com 200319475328460096299 200319475328460096299 No School of Medicine, Semnan University of Medical Sciences, Semnan, Iran Maliheh Yarmohamadi Yarmohamadi_mal212@gmail.com 200319475328460096300 200319475328460096300 No Department of Internal Medicine, School of Medicine, Semnan University of Medical Sciences, Semnan, Iran Kamyar Mansori kamyarmansori@yahoo.com 200319475328460096301 200319475328460096301 No Clinical Research Development Unit, Valiasr Hospital, Zanjan University of Medical Sciences, Zanjan, Iran Mohammad Memarian dr.memarian20@gmail.com 200319475328460096302 200319475328460096302 Yes School of Medicine, Semnan University of Medical Sciences, Semnan, Iran
