WebbA q-wave is an initial downward deflection in the QRS complex. These are normal in left-sided chest leads (V5, 6, lead I, aVL) as they represent septal depolarization from left to right. This is as long as they are <0.04secs long (1 small square) and <2mm deep. If q-waves are larger than this or present in other leads they are pathological. Webb22 sep. 2024 · The differential diagnosis of T-wave inversions includes: pulmonary embolism; intracranial hemorrhage; myocardial ischemia (coronary T-waves, or Wellens’ syndrome); cardiomyopathies or myocarditis; electrolyte abnormalities, especially hypokalemia; and normal variants. Ischemic T-wave inversions are classically symmetric.
