The purpose of this study is to examine the electrocardiographic features of patient stung by scorpions.


Seventy six patients stung by scorpions were gathered in the study. 12 lead derivations electrocardiography (ECGs) was performed to all patients. The ECG which were performed when the patients had maximum (grade 3) pain were obtained for determination. The determined parameters were: PR segment and QRS duration, QTmin, QTmax, QTc, QT dispersion (QTd) intervals, minimum P wave duration (PWmin), maximum P wave duration (PWmax) and P wave dispersion (PWd).


Seventh six patients (37 males and 39 females, mean age: 33,7±14,7 years) were included in this analysis. Heart rate, QRS duration, QTc, QTd, PWmin, and PWd which we found were 84,5±13,8 beat/min, 98,8±11,8 msn, 412±27,4 msn, 412±27,4 msn, 412±27,4msn and 41,4±19,7 msn respectively.


Scorpion sting lead electrocardiografic variability. The most common changes were ST changes, sinus tachycardia, atrial ectopic beat, bradycardia, and ventricular ectopic beat.
