WebTheoretically, the delta wave should be present in all leads, but it may become isoelectric and be easily overlooked in the leads with the lead axis, which is nearly perpendicular to the initial QRS forces. When the delta wave is negative, the downward deflection may resemble the abnormal Q wave associated with myocardial infarction. WebVerified answer. engineering.
