SANCHEZ SANCHEZ, Samuel; ECHAZABAL LEAL, Magdiel; NAVARRO BALDELLOT, Ana Laura y SANCHEZ RAMOS, Emmanuel. Characterization of patients with bradyarrhythmias treated at the Cienfuegos Cardiology service (2018-2019). Medisur [online]. 2020, vol.18, n.6, pp. 1110-1121. Epub 02-Dic-2020. ISSN 1727-897X.
Background:
The creation of a bradyarrhythmias consultation in Cienfuegos, since 2017, has made possible the treatment and more specific follow-up of affected patients. Therefore, the study of its clinical and paraclinical characteristics is relevant.
Objective:
to characterize patients with non-reversible bradyarrhythmias from the clinical point of view.
Methods:
an observational, descriptive, cross-sectional study was carried out. All the patients seen by the Cardiology Service with a diagnosis of non-reversible bradyarrhythmia (N = 214) were taken into account to this work. Clinical, electrocardiographic, ergometric and echocardiographic variables were studied. Each one was given the statistical treatment according to its distribution, scale and type.
Results:
Male sex predominated. The median age was 74 years. Hypertension was the most frequent comorbidity. The echocardigraphic study showed some type of structural alteration in the 80% of the patients. The most common etiology was fibrosis of the excito-conductor system (77%), as well as third degree atrioventricular block was the most common electrocardiographic diagnosis among those who received temporary and permanent pacemaker implantation. There was a low rate of complications.
Conclusion:
the studied population was characterized as aged; with the presence of comorbidities; with some type of structural alteration in the majority, demonstrated through echocardiographic study. Fibrosis of the excito-conductive system and ischemic were the main causes of non-reversible bradyarrhythmia.
