We have to see the EKG in actual for the proper interpretation. Anyway I am here to help you in anyway. The causes of left axis deviation may be: Left ventricle gets enlarged. There is some kind of block in the conduction system of the heart that transmits the electrical impulses in heart. People with genetic defects in heart (ASD) may have such an EKG. Wolff-Parkinson White is a syndrome in which again there is an issue with the electrical activity of the heart. Last but not the least this kind of EKG can also be seen in totally normal people who are OBESE. So physical examination and to see the EKG in real is necessary for commenting on that. Consult a cardiologist in-person for more help. Hope I answered all of your questions.
