"Webb16 juni 2024 · Conclusion. Delta waves ECG indicates that there is an additional channel carrying electricity from the atria to the ventricles. In the QRS complex, the Delta wave is a slurred upstroke. It is related to pre-excitation of the ventricles and so frequently results in a shortening of the PR interval. It is most usually linked to pre-excitation ... " - Slurred q wave
