Incidence and characteristics of atrial high-rate episodes in patients with implantable cardiac devices

Abstract

Background: The most prevalent persistent arrhythmia is atrial fibrillation (AF), which is frequently linked to a high risk of morbidity and mortality. Despite the increasingly recognized integrated management as anticoagulation treatment in AF patients, Still, a sizable proportion of people are suffering from AF. admitted with heart failure, stroke, and other comorbidities. This is explained by the asymptomatic nature of AF. The aim of this work was to assess how frequently atrial high-rate events occur in patients with implantable cardiac devices and to determine their characteristics. Methods: This prospective observational study was conducted at Tanta University Hospital on patients with implantable cardiac device who attended the cardiovascular outpatient clinic. All patients gave their informed consent. The inclusion criteria included patients with implantable cardiac device that includes an Atrial lead. Results: Regarding the demographic characteristics, our study revealed no significant connection between atrial high-rate episodes (AHRE) detection with both age (P = 0.897) and gender (P = 0.624) of the patients. The general medical history of included patients revealed no significant association with AHRE except for ischemic heart disease (IHD) patients. Conclusions: Patients with cardiac implanted devices experience a significant incidence of AHREs. It is likely that AHRE will be reported more frequently in the future due to improvements in cardiac monitoring. Previous research showing a strong link between AHREs and clinically verified AF has been used to support this viewpoint.
