ABSTRACT

Introduction. Mexico is a country with a high incidence of scorpion stings due to the diversity therein, with Guanajuato being one of the Mexican states with the highest reports of scorpion sting, the objective was: to evaluate electrocardiographic abnormalities during scorpion sting poisoning related to the increase in blood pressure.
Methods. All individuals treated for scorpion sting at the Centro antialacran de la Cruz Roja Mexicana in Guanajuato, Mexico were analyzed. Vital signs were recorded: heart rate, respiratory rate, blood pressure, and an electrocardiogram was performed at admission and discharge. A description of the characteristics of the individuals was made and analytical statistics were used to assess differences between income and discharge. Also, correlations between the studied variables were sought.
Results. Eleven individuals with scorpion sting poisoning, older than 18 years and without a history of chronic diseases were included. The totality of the individuals presented hypertension; and 90.9% presented deviation of the cardiac axis. Systolic blood pressure at admission and the initial QRS segment had a correlation of 0.639 (p = 0.017); while the diastolic blood pressure at admission and the initial QRS segment had an inverse correlation of 0.66 (p = 0.014). No mortality was recorded.
Discussion. Electrocardiographic changes and alterations in blood pressure after scorpion sting are common.
