When the delta wave is negative, the downward deflection may resemble the abnormalQ waveassociated withmyocardial infarction. Such a pseudoinfarction pattern may be seen in up to 70 percent of patients with the
A selected number of electrocardiographic il lustra I ions of the WPW syndrome is presented, emphasizing the variability in the morphology of the delta wave. This versatility is shown (o be a function of available vagal tone. It is postulated that the delta wave is an autonomic supraventricular...
The delta wave represents the presence of accessory electrical tissue from atria to ventricle, with rapid antegrade conduction causing excitation of ventricular tissue before atrioventricular node–His bundle stimulation. From: Nelson Pediatric Symptom-Based Diagnosis, 2018 ...

A delta wave refers to a slow conduction through the bypass tract and ventricular myocardium in the heart. It is an important finding in the WPW pattern and is characterized by a duration of 0.02 to 0.07 seconds. The delta wave may resemble an abnormal Q wave associated with myocardial infarc...
