At the end of year 2019, the world faced an outbreak of a highly virulent novel Coronavirus disease (COVID-19), which changed the way physicians, including cardiologists, do their routine clinical practice. As distance limitation and efficient use of personal protective devices must be employed to prevent the pandemic spreading, even simple electrocardiogram (ECG) taking that involves directly placing electrode leads on a patient’s body may become riskier. This review will discuss the possibility of minimal or no touch EKG using the latest wireless technologies, beneficial in monitoring COVID-19 patients for cardiovascular problems or patients who seek cardiac care, but with posing risk of concomitant COVID-19.
Background: Due to its adverse outcomes and thromboembolic complications, early detection of atrial fibrillation (AF) is advisable in the general population. This study aims to compare the diagnostic ability of two distinct method in smartphone application format, namely : AliveCor KardiaMobile and FibriCheck. Methods: This study was conducted in Mohammad Hospital General Hospital Palembang with convenience sampling of 170 participants aged 18 years or older. The subjects underwent Fibricheck and KardiaMobile recordings followed by 12 lead electrocardiogram read by board-certified cardiologist as the diagnostic standard. Results: After the exclusion of previous pacemaker implantation (n=7), 163 patients were included in the study. The mean age was 51±15 years with gender distribution of 74.8% men and 25.2% women. Most of the subjects were asymptomatic (87.1%) with mean blood pressure of 130/80 mmHg. The Fibricheck readings showed sensitivity of 73% and specificity of 93%, meanwhile Kardiamobile was able to detect AF with sensitivity of 77% and specificity of 98%. Conclusion: In our study, KardiaMobile demonstrated overall greater sensitivity and specificity when compared to FibriCheck. However, KardiaMobile requires an external metal sensor that must be puchased separately. To the best of our knowledge, this is the first study to directly compare both methods in the Indonesian population.
Aims The aim of the current study was to evaluate P wave abnormalities, including prolonged P wave duration, prolonged P wave dispersion (PWD) and abnormal P wave axis (PWA) in newly diagnosed COVID-19 patients. Methods and Results This is a cross-sectional, single center study with a total of 53 newly diagnosed COVID-19 patients (confirmed with polymerase chain reaction (PCR) test) and 63 age and sex-matched control subjects were included in the study. P wave dispersion, maximum P wave duration, and PWA were calculated manually from 12-lead ECG. Patients with COVID-19 more often had prolonged PWD, defined as PWD ≥ 36 ms compared to control group (37,7% vs 15,9%), (OR = 3,212; 95%CI 1,34 – 7,70; p = 0,007). There were no significant association between COVID-19 and prolonged P wave (defined as maximum P wave duration > 106 ms) (OR = 1,446; 95%CI 0,454 – 4,6; p = 0,531) and abnormal PWA (defined as any value of PWA outside 0 to 75°) (OR = 5,061; 95%CI 0,548 – 46,74; p = 0,115). Conclusion Our study showed that COVID-19 patients are more likely to have prolonged PWD compared to control patients. However, COVID-19 was not significantly associated with prolonged P wave and abnormal PWA. We believe that initial non-invasive evaluation of PWD may serve as a predictor of atrial arrhytmias often found in COVID-19 patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
