WebThe presence of unexpected Q waves in an applicant's electrocardiogram poses a diagnostic dilemma for the medical director. On the one hand, the Q waves may be the remnants of a previously unsuspected "silent" myocardial infarction. Conversely, unexpected Q waves may represent a normal or positional variant, or an important noncoronary type of ... WebSmall Q waves are present in the left precordial leads in more than 75 percent of normal subjects. They are seen most frequently in lead V6, less frequently in leads V 5 and V 4, and rarely in V 3. Q waves in these leads are present more often in young subjects than in subjects older than 40 years.
