axis deviation

Usually this would show as an extreme axis deviation.

The ventricular beats typically have a right axis deviation.

It is manifest on the ECG by left axis deviation.

A small degree of axis deviation may be made manifest with powerful reading glasses causing difficulty in binocular vision when these are worn.

In the setting of right bundle branch block, right or left axis deviation may indicate bifascicular block.

The electricity then has to go through the other fascicle, and thus is a frontal right axis deviation seen on the ECG.

Marked axis deviation, bundle branch block, and AV block are common, as is atrial fibrillation.

The most commonly seen signs in the ECG is sinus tachycardia, right axis deviation and right bundle branch block.

Between +90 degrees and +180 degrees the condition may be termed Indeterminate Deviation or more often Extreme Right Axis Deviation.

Individuals with a sinus venosus ASD exhibit a left axis deviation of the P wave (not the QRS complex).

An ECG with right ventricular hypertrophy may or may not show a right axis deviation on the ECG.

Left axis deviation (LAD) is a condition whereby the mean electrical axis of ventricular contraction of the heart lies in a frontal plane direction between -30 and -90 .

When left bundle-branch block (LBBB) is accompanied by right axis deviation (RAD), the rare combination is considered to be highly suggestive of dilated or congestive cardiomyopathy.

The delayed and unopposed activation of the remainder of the left ventricle now results in a shift in the QRS axis leftward and superiorly, causing marked left axis deviation.

It is important not to call LAFB in the setting of a prior inferior wall myocardial infarction which may also demonstrate left axis deviation due to the initial forces (Q wave in a Qr complex) in leads II, III, and aVF.

In addition to the PR prolongation, individuals with a primum ASD have a left axis deviation of the QRS complex while those with a secundum ASD have a right axis deviation of the QRS complex.
