Has anyone been told that their ECG suggest the left wall of the heart is enlarged? My doctor things this is because of my cycling and having a thin chest wall. I guess at 130 pounds and 5 foot8 the program on the ECG reads my result as LVH. She said that one study she saw sugggest that 40% of competive cyclist showed this on their ECG but less then 5% really had any change in heart structure (by echocardiogram). But because of the 5% I need a echo anyway.
