In 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°.
9 Σεπ 2024 · Abnormal axis deviation, indicating underlying pathology, is demonstrated by: Left Axis Deviation = QRS axis less than -30°. Right Axis Deviation = QRS axis greater than +90°.
Left-axis deviation is when the QRS axis is between -30° and -90º. Moderate left-axis deviation is between -30° and -45°. Marked left-axis deviation is from -45° to -90° and is often associated with left anterior fascicular block 1. The situations in which left-axis deviation may be seen are as follows:
If the axis is more positive than 90° it is referred to as right axis deviation. If the axis is more negative than –30° it is referred to as left axis deviation. The axis is calculated (to the nearest degree) by the ECG machine.
8 Ιαν 2024 · Identify the key components of electrical axis deviation on an electrocardiogram. Differentiate between right-axis deviation and left-axis deviation based on electrocardiogram patterns. Apply knowledge of vector analysis to interpret electrocardiograms and determine the electrical axis.
6 Μαρ 2011 · Left axis deviation. Left axis deviation (LAD) involves the direction of depolarisation being distorted to the left (between -30º and -90º). This results in the deflection of lead III becoming negative (this is only considered significant if the deflection of lead II also becomes negative).
