Left and right axis deviation
NettetWhat does left and right axis deviation mean? If the electrical axis falls between the values of -30 to +90 this is considered normal. If the electrical axis is between -30 to -90 this is considered left axis deviation. If the electrical axis is between +90 to +180 this is considered right axis deviation (RAD). NettetLeft axis deviation • LV strain pattern, which correlates with LV dilatation and hypertrophy • Normal sinus rhythm is the usual pattern; in case of AF, HF or the presence of the mitral disease should be considered.
