WebA vertical or slightly right axis is normal in young people. Older people often have a left axis as the left ventricle tends to grow with age, effort and higher blood pressure. In addition, with higher heart rate (from 80 and higher) the axis tends to turn rightwards. From 130 and above, it turns leftwards again, and I have no idea why :) WebThe normal newborn ECG should include 12 leads. Other leads, V 3R,V 4R and V 7, may provide additional information to evaluate possible congenital heart lesions.
