Differential diagnosis of wide complex tachycardia
- I. interní klinika Fakultní nemocnice v Hradci Králové
Initial evaluation of every tachyarrhythmia begins with question whether the QRS complex is wide or narrow. Most important cause of wide complex tachycardia (WCT) is ventricular tachycardia (VT). A narrow complex usually indicates supraventricular tachycardia (SVT), however, SVT can also manifest as a WCT. Differentiation between SVT with a wide QRS due to aberrancy or preexcitation and VT often present a diagnostic challenge. The identification of the origin is critical because the treatment for each is different and improper therapy may have serious consequences. Following report is focused on differential diagnosis particularly using standard 12-lead ECG.
