The frontal plane QRS axis of the standard 12-lead electrocardiogram (ECG) is easily and accurately measured by the clinician. A simple method of estimating this axis is discussed. This axis is age-dependent. We reviewed the literature to determine if evidence exists of an association between an “abnormal” QRS …

Cardiac axis in electrocardiography represents the sum of depolarization vectors generated by individual cardiac myocytes. To interpret the cardiac axis, one has to determine the relationship between the QRS axis and limb leads of the ECG. Usually, left ventricles makes up most of the heart muscles, so a normal cardiac axis is directed downward and slightly to the left. In a normal axis, QRS is between -30° and +90°. In contrast to that, left axis deviation (LAD) is defined as Q… NettetLeft axis deviation occurs in about 4 percent of those with an isolated ventricular septal defect. 9 In patients with cyanotic heart disease, left axis deviation is seen typically in those with tricuspid atresia and often in patients with a single ventricle. 16 Isolated congenital left axis deviation without evidence of heart disease also has …
