ABSTRACT
Introduction: electrocardiographic abnormalities due to electrical burns occur in a minority of patients but can be serious and fatal.They usually manifest early, especially in the first 24 to 36 hours, but can sometimes be late and usually occur during high-voltage electrical discharges. For this reason, each patient must be carefully evaluated to establish an appropriate diagnosis and treatment.
Objective: to determine the frequency and type of electrocardiographic alteration associated with electrical burn in adult patients who attended the Dr. Rubén Leñero General Hospital during the period January-December 2022.
Methods: a clinical epidemiological study was carried out with a quantitative, observational, descriptive, analytical, cross-sectional and retrospective approach in patients with electrical burn admitted to the emergency service of the Dr. Rubén Leñero General Hospital with an electrocardiogram upon admission during the period January-December 2022. The risk of ventricular arrhythmias was assessed by calculating the Tpeak-Tend (Tpe) interval, an index used to assess ventricular repolarization.
Results: after applying the selection criteria, we obtained a sample of 40 patients in the period studied, 37 were men and 3 were women. 28 (70%) were reported with sinus rhythm, 5 (13%) sinus bradycardia, 5 (13%) sinus tachycardia, 1 (2%) posterior fascicular block and 1 (2%) with Mc Ginn White complex. It was found that the risk index to evaluate ventricular repolarization by means of the Tpeak-Tend interval was greater than 90 milliseconds with a mean of 96 and SD of 19.77 for direct electric current; mean of 93 and SD of 20.22 for electric arc. The student T is 1.96 with a significance level of 0.05, with no statistically significant difference.
Conclusions: electrocardiographic alterations due to electrical burns are considered to be rare, although there may be a risk of presenting ventricular arrhythmias, with ventricular fibrillation being fatal.
