Deciphering wide QRS complex: The quest continues

Wide QRS complex (WCT) tachycardias pose a diagnostic dilemma: should we diagnose a ventricular tachycardia (VT) or is this some form of tachycardia that requires structures above the bundle of His, i.e. a supraventricular tachycardia (SVT)? All ECG-based approaches to a WCT diagnosis can be grouped into three categories 1.) a “yes” or “no” method based on a single criterion/composite criterion (all “algorithms” are a composite criterion in their essence), 2.) the Bayesian method based on multiple criteria and the likelihood ratio for a VT diagnosis, and 3.) / VT score method, which is methodologically somewhe re in between the first and second approach.
