All the other cases (124 cases) had situs solitus, levocardia and left cardiac axis between 60[degrees] and 90[degrees].
Generally, intrinsic congenital heart diseases cause abnormal cardiac axis (17, 18).
Bundles of cardiomyocytes are slightly curved and oriented along the longitudinal cardiac axis
. In the 2-3 mm after NAV, the number of cardiomyocytes in the bundle increases.
For instance, Bilora and coworkers reported that obese patients presented a shorter PQ, a prevalence of left cardiac axis
, a higher heart rate, a longer QT, but not QTc compared with normal males; however there was no correlation between QTc and obesity (2).
The finding of an abnormal cardiac axis
is one of the markers that should prompt further evaluation, she said.
