Significance of a Q wave in lead I in the newborn

Am J Cardiol. 1999 Sep 1;84(5):615-7, A9. doi: 10.1016/s0002-9149(99)00394-x.

Abstract

We present 11 healthy newborns whose electrocardiograms had a pure Q wave in lead I and who did not have a myocardial infarction clinically. We propose that in the healthy newborn, a pure Q wave in lead I may be due to increased right ventricular mass, not myocardial infarction.
