Sinus arrhythmia: clinical case

Abstract

Introduction. Sinus arrhythmia is a heart rhythm disturbance that does not present symptoms or show abnormalities in the sinus node. The most common cause is brain injury, caused by increased intracranial pressure or hypoxia, which often manifests in young healthy people by heart rate variability below normal and increased vagal tone. Objective. To determine the management of sinus arrhythmia by analyzing a clinical case to present new and instructive aspects of the disease. Methodology. A retrospective descriptive study through the analysis of a clinical case and for the collection of information about the pathology, searches will be made in the different scientific sources of the last 5 years in platforms such as: Scopus, PorQuest, PudMed, Web of Science, Lilacs, Redalyc, Medigraphic, Scielo, among others.  Results. A 14-year-old male patient in Guatemala went to the cardiology emergency department for cardiac rhythm assessment, 3 electrocardiograms were taken and a diagnosis of electrocardiogram of an athlete with a heart rate of 28 bpm was made. Conclusion. The importance of this research work is to describe the clinical case of a 14-year-old male patient with sinus arrhythmia and to analyze new and instructive aspects of the disease and acquire new knowledge about the pathology. General area of study: medicine. Specific area of study: cardiology. Type of study: clinical cases.
