I had a pre-surgical ecg. the result is like : normal sinus rhythm left axis deviation abnormal ecg what does it mean?

Axis: The preponderance of electrical activity of your heart is directed to the left of your body. This may mean your left ventricle is thickened (hypertrophy), or may be caused by a minor conduction delay (left anterior hemiblock). Neither of these are very serious, and will probably not delay your surgery. Ask your doc about your ekg findings.

Ecg : The ECG with normal sinus rhythm and left axis deviation does not imply any serious abnormality.
