30 TO -60 degree axis detion is seen in:: (A) Left Ventricle Hyperophy, (B) Right Ventricle Hyperophy, (C) Left Posterior Fascicular Block, (D) Lateral wall Myocardial Infarction
Answer is A. Answer is A (Left Ventricle Hyperophy): Detion of the cardiac axis more negative than -30 (Between -30 to -90) indicates Left Axis Detion. Left Ventricular Hyperophy is the most common cause of left axis detion. Right Ventricle Hyperophy, Left Posterior Fascicular Block and Lateral wall Myocardial Infarction are all associated with Right Axis Detion.
