WebThe electrical axis of the heart is normally between -30˚ and +90˚, and may vary by up to 35˚ during normal breathing due to the associated movements of the heart (Moody et al., … 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. [1] There are several potential causes of LAD.
