RESUMEN

Introducción:

el intervalo QTc prolongado ha sido identificado como factor de riesgo en arritmias ventriculares e incluso muerte súbita.

Objetivo:

establecer la prevalencia de QTc prolongado en pacientes internados.

Metodología:

estudio observacional, descriptivo, prospectivo que incluyó 123 pacientes internados en el Servicio de Clínica Médica y salas de urgencias del Hospital Nacional en 2014. Se consideró como QTc prolongado un valor > 0,44 seg en varones y >0,46 seg en mujeres en 4 derivaciones aVL, DII, V5 y V6.

Resultados:

la prevalencia de QTc prolongado fue 26%, con predominio del sexo masculino (71%). La principal comorbilidad asociada fue la diabetes mellitus. Los electrolitos K+, Ca+2, Mg+ estaban bajos en la mayoría de estos afectados. El 16% de los pacientes con QTc prolongado terminaron en óbito.

Conclusiones:

se halló alta prevalencia de QTc prolongado (26%). Se requieren estudios más complejos para determinar la asociación de esta patología con las comorbilidades, los cuadros neurológicos, el uso de medicamentos y las alteraciones de los electrolitos detectadas.
ABSTRACT

Introduction:

The prolonged QTc interval has been identified as a risk factor for ventricular arrhythmias and even sudden death.

Objective:

To establish the prevalence of prolonged QTc in hospitalized patients.

Methodology:

Prospective descriptive observational study that included 123 patients hospitalized in the Service of Medical Clinic and urgency rooms of the National Hospital in 2014. A value > 0.44 seg in men and >0.46 seg in women for 4 derivations aVL, DII, V5 and V6Se were considered as prolonged QTc.

Results:

The prevalence of QTc was 26% with a predominance of men (71%). The main associated comorbidity was diabetes mellitus. K+, Ca+2 and Mg+ electrolytes were low in most patients. A 16% of the patients with prolonged QTc died.

Conclusions:

A high prevalence (26%) of prolonged Qtc was found. More complex studies are required to determine the association of this pathology with the comorbidities, neurological symptoms, use of medicines and alteration of electrolytes detected.
