Abstract

Background Differential diagnosis of wide QRS complex tachycardias using the 12-lead ECG may be difficult in many clinical settings.Objective The purpose of this study was to determine the value of ECG lead II, specifically, the duration at its beginning, defined as R-wave peak time (RWPT), in differentiating ventricular tachycardia (VT) from supraventricular tachycardia (SVT) in patients with wide QRS complex tachycardia.Methods Two hundred eighteen ECGs showing wide QRS complex tachycardias were evaluated. Two cardiologists blinded to the diagnosis measured RWPT duration at lead II (from the isoelectric line to the point of first change in polarity), and results between VT and SVT were compared, with the findings of electrophysiologic study used as the gold standard.Results One hundred sixty-three VTs had a significantly longer RWPT at DII (76.7 +/- 21.7 ms vs 26.8 +/- 9.5 ms in 55 SVT, P = .00001). Receiver operating characteristic curve identified RWPT > or =50 ms at lead II as having greater specificity and sensitivity in discriminating VT from SVT. Area under the curve was 0.97 (95% confidence interval 0.95-0.99), positive likelihood ratio was 34.8, and kappa coefficient (kappa) was 0.86. Bivariate analysis identified higher age in VT patients (60.7 vs 50.1 years, P < or =.01) and wider QRS complex duration at lead II in VT patients (169.4 vs 128.3 ms, P <.0001). QRS width at DII was not superior to RWPT in diagnosing VT.Conclusion RWPT > or =50 ms at DII is a simple and highly sensitive criterion that discriminates VT from SVT in patients with wide QRS complex tachycardia.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
