 [ Symptoms ] ekg says there was “moderate right axis deviation ” “normal sinus rhythm with marked sinus arrythmia ” [ Disease ] hi right axis deviation in ekg means a high amplitude recording on right side of the heart chambers having only right axis deviation is not significant enough to label you as having a major heart disease unless its accompanied by other positive findings get a 2 d echo to confirm and get a second opinion from a cardiologist to be on a safer side thanks
