Overview
Right Axis Deviation (RAD) is a heart condition where the electrical conduction of the heart is greater than +105 degrees or between -90 degrees and +180 degrees (may be called Indeterminate) or more often extreme Right Axis Deviation. The degrees may be determined by a 12-lead ECG (EKG=German).
Right axis deviation EKG examples
The below EKG image shows
- Right axis deviation (> 90°)
- R/S ratio of more than 1
- T wave inversion in right precordial leads indicating strain pattern
- Abnormal P wave in V1 indicating left atrial abnormalities
