WebDetails. Q waves do not always indicate infarction. Must distinguish normal septal q waves from pathologic Q waves: Normal septal q wave: <0.04s, low amplitude. Abnormal septal q wave: >0.04s in I OR in II, III, AND aVF OR V3, V4, V5, AND V6. Q-wave equivalents in the precordial leads: R-wave diminution or poor R-wave progression. WebLeft anterior fascicular block (LAFB) is an abnormal condition of the left ventricle of the heart, 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.It is much more common than left posterior …

WebIn electrocardiography, left axis deviation (LAD) is a condition wherein the mean electrical axis of ventricular contraction of the heart lies in a frontal plane direction between −30° and −90°. This is reflected by a QRS complex positive in lead I and negative in leads aVF and II.. There are several potential causes of LAD. Some of the causes include normal variation, …

WebThe formal threshold for left anterior fascicular block (LAFB) is −45° not −30°, the latter being the cutoff for left axis deviation. LAFB, by itself, may widen the QRS slightly but usually not beyond 0.11–012 sec. Most cases of pure LAFB are associated with small r waves in the inferior leads and a small q wave in lead aVL. WebJul 14, 2009 · Around V3 or V4 the R waves become larger than the S waves and this is called the 'transitional zone'. If the transition occurs at or before V2, this is called counterclockwise rotation. If the transition occurs after V4, this is called clockwise rotation. Several studies have been done to understand the anatomical substrate for these rotations.
