Thiruvenkatarajan V, et al. - The ‘torsadogenic’ property of a drug is linked to its ability to increase the transmural dispersion of repolarisation, represented by the interval between the peak of, and the end of, the T-wave (Tp-e interval) in an electrocardiogram. Whether sevoflurane increases the Tp-e interval and Tp-e/QTc (rate-corrected QT interval) ratio in patients with diabetes, thereby increasing their risk of torsades, was ascertained in this current study. In the absence of other factors affecting ventricular repolarisation, no significant predictable pro-arrhythmic effect of sevoflurane was apparent in type 2 diabetic patients.
