Leftward axis deviation
NettetLeft anterior fascicular block (LAFB) is an abnormal condition of the left ventricle of the heart, [1] [2] related to, but distinguished from, left bundle branch block (LBBB). It is caused by only the left anterior fascicle – one half of the left bundle branch being defective. It is manifested on the ECG by left axis deviation. NettetThis QRS orientation is equivalent to an angle alpha of +30° to +90°; (2) left axis deviation (LAD) exists when the over all QRS area is positive in leads 1 and aVL and negative in …
