Webb28 jan. 2024 · The ECG will show a short PR interval (&lt;120 ms), prolonged QRS complex (&gt;120 ms), and a QRS morphology consisting of a slurred delta wave. The preexcitation of the ventricle causes this morphology through the accessory pathway that forms a fusion complex with the normal QRS complex arising from normal cardiac conduction. Webb6 dec. 2024 · As you can seen on the ECG example below the ST elevation in the precordial leads is slurred upwards, and the elevation is widespread across the ECG. High-take off can also be confused with pericarditis for this reason. Generally the ST elevation is minimal and each lead has its own defined T waves. There is also no ST depression on the ECG.
