This letter discusses the methodological classification of pre-excited tachycardias when evaluating electrocardiographic algorithms for wide QRS-complex tachycardias.
We read with interest the article by Jastrzebski et al .1 about the head-to-head comparison of five electrocardiographic (ECG) methods for the differentiation of wide QRS-complex tachycardias (WCT). They also included 23 pre-excited tachycardias (PXT) in the supraventricular tachycardia (SVT) group. Although it was not clear from the article, Dr Jastrzebski answered our e-mail enquiry regarding when the mechanism of WCT was PXT and the final diagnosis made with our aVR algorithm2 or the Brugada algorithm3 or the lead II R-wave peak time (RWPT) criterion4 was ventricular tachycardia (VT), they considered it as an incorrect diagnosis …
