| Abstract [eng] |
The challenge of managing patients with syncope of unknown origin, whose etiology cannot be ascertained despite extensive non-invasive and invasive testing, presents a therapeutic dilemma. Diagnosis is further complicated by the sporadic and unpredictable nature of syncopal episodes. In this context, long-term monitoring using an implantable loop recorders (ILR) offers distinct advantages over other diagnostic modalities. By continuously monitoring the cardiac rhythm over extended periods, ILR increases the likelihood of establishing a correlation between the recorded events and the cardiac rhythm. This feature enhances the diagnostic utility of ILR and renders them a valuable tool for clinicians in the diagnosis and management of patients with syncope of unknown origin. The purpose of the study is to analyze scientific publications on the use of implantable loop recorders for syncope diagnosis and to compare their diagnostic efficiency with conventional syncope diagnosis. Research material and methods. Scientific literature was searched in databases PubMed, Science Direct, Cohrane Library, specialized information search system Google Scholar. Keywords and their combinations were used for the search: implantable loop recorder, syncope, diagnostics, arrhythmia. The most relevant scientific articles written in English, corresponding to the purpose of the work, and their sources were selected. Conclusions. The diagnostic effectiveness of ILR in identifying the origin of syncope is significantly greater than that of other diagnostic tools. In patients presenting with syncope of unknown origin and the absence of structural heart disease, bradyarrhythmias rank among the most prevalent causes of syncope. Given this fact, early consideration of initiating long-term monitoring with an ILR is of paramount importance. |
