If the electrical axis is between -30° and -90° this is considered left axis deviation. If the electrical axis is between +90° and +180° this is considered right axis deviation (RAD). RAD is an ECG finding that arises either as an anatomically normal variant or an indicator of underlying pathology.
Nonetheless, the ECG is used to assist with the diagnosis of RVH. A post mortem study on 51 adult male patients concluded that anatomical RVH may be diagnosed using one or more of the following ECG criteria: [8] Right axis deviation of more than (or equal to) 110° (see hexaxial reference figure) R-wave dominant over S-wave in V1 or V2

A right bundle branch block typically causes prolongation of the last part of the QRS complex and may shift the heart's electrical axis slightly to the right. The ECG will show a terminal R wave in lead V1 and a slurred S wave in lead I. Left bundle branch block widens the entire QRS, and in most cases shifts the heart's electrical axis to the ...
Technical dextrocardia refers to an ECG reading that has no basis in the patient's anatomy. This apparent presentation is typically caused by the accidental lead placement of the left and right arm electrodes. Usually, this would show as an extreme axis deviation. [citation needed]
Lots of foods you probably already eat are high in magnesium. The best sources of magnesium are dark leafy greens like spinach or swiss chard, as well as nuts and seeds. Almonds, cashews, pumpkin ...

There should be a terminal R wave in lead V 1 (often called "R prime," and denoted by R, rR', rsR', rSR', or qR). There must be a prolonged S wave in leads I and V 6 (sometimes referred to as a "slurred" S wave). The T wave should be deflected opposite the terminal deflection of the QRS complex.
