What does right axis deviation in ECG mean?

Right Axis Deviation = QRS axis greater than +90° Normal Axis = QRS axis between -30° and +90° Left Axis Deviation = QRS axis less than -30° Extreme Axis Deviation = QRS axis between -90° and 180° (AKA “Northwest Axis”)

Considering this, is right axis deviation normal?

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).

Additionally, what causes extreme axis deviation? Causes of extreme axis deviation Most likely due to misplaced limb electrodes. If the rhythm is tachycardia with wide QRS complexes, then ventricular tachycardia is the most likely cause.

Besides, what does axis deviation mean on ECG?

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°. This is reflected by a QRS complex positive in lead I and negative in leads aVF and II.

Is right axis deviation life threatening?

Although not a dangerous finding in and of itself, axis deviation may be an indication of a serious underlying condition.
