The objective of this study is to examine the electrocardiographic features of patient stung by scorpions.
Forty patients stung by scorpions were gathered in the study. 12 lead derivations electrocardiography (ECGs) was performed. 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).
19 males and 21 females (mean age: 34.7±14.7 years) were included in this analysis. Heart rate (83, 5±13, 8 beat/min), QRS (96, 8±11, 8 msn), QTc (414±27, 4 msn), QTd (412±27, 4 msn), PWmin (412±27, 4msn) and PWd (41, 4±19, 7 msn) were found. Scorpion sting lead to electrocardiographic variability.
The commonest changes included were ST changes, sinus tachycardia, atrial ectopic beat, bradycardia, and ventricular ectopic beat.
