ABSTRACT
Objective. To determine prevalence and frequency distribution of electrocardiographic alteration in users from a private Unit of Clinical Analysis Unit.Material y Methods. This is a retrospective and cross-sectional study, which included 112 patients from the electrocardiography service. Using for sampling no randomized method for convenience. The selection criteria were patients from any age and gender, attended during July 2012 from July 2013 with complete medical file. The analyzed variables were age, gender, cardiac frequency, PR interval duration, QRS complex duration, QRS axis, QT interval duration, QTc interval duration and diagnosis. For diagnosis a 12 derivations digital electrocardiograph Dr. ECG® RT100 distributed by SIMEDIC® was used. The electrocardiograms were interpreted by cardiologist by telemedicine. Descriptive statistic were applied. The software used were Microsoft Excel© 2010 and SPSS© 15.0.
Results. From the 112 electrocardiographic studies were included, 63.4% were from females. The mean age was 45.06±19.91 years. 71.4% of the analyzed were adults, 22.3% elderlies and 6.3% pediatrics. The abnormal electrocardiogram prevalence was 33%. The most frequent electrocardiographic alterations were sinusal bradicardia in 28% and anterosuperior fascicle block of His Bundle in 21%.
Conclusion. The majority of users are adults; considering this and the heterogeneity of the study population, the prevalence of electrocardiographic alteration was found in the mean. Consistent with the literature, the Bundle of His blocks are among the most frequent alterations. In this cohort, sinusal badycardia was unusually frequent to what was expected.
