It is not only incomprehensible, it is just incorrect. Right axis deviation is not necessarily congenital, and has nothing to do with being congenital. It is simply a finding on electrocardiogram that describes the direction (axis) of electrical conduction through the heart using the standard electrocardiogram leads. The direction of electrical conduction through the heart changes dependent on a few factors, some of which can be congential, but others that are clearly acquired (such as a heart attack leading to fibrotic heart tissue that is no longer electrically conductive).

Figure 3 is wrong.
The normal axis is from -30 to +90. The perpendicular axis to -30 is lead II. Therefore an axis of -30 is isoelectric in lead II. With left axis deviation, lead II becomes negative.
From "The ECG Made Easy" by John Hampton, 8th edition, page 16: "If in lead II the S wave is greater than the R wave, the axis must be more than 90° away from lead II. In other words, it must be at a greater angle than -30°, and closer to the vertical, and left axis deviation is present." Axl ¤ [Talk] 12:06, 20 November 2016 (UTC)
