WebQ waves are often present in the lateral and inferior leads and in lead aVR, but they should be narrow (<40 msec) and shallow (age-dependent but usually <5-mm deep). Deep or wide Q waves suggest myocardial ischemia and require further evaluation. An uncommon but crucial finding occurs in infants with ALCAPA. WebMar 4, 2008 · The consistent regression of Q waves in our patients, however, suggests that the pathologic Q wave in ALCAPA does not necessarily imply irreversible myocardial damage. Instead, the jeopardised myocardium may be caused by ischaemia or stunning, but it may still be, at least in part, viable after restoration of the dual coronary supply.
