In this paper we have projected a new methodology to characterize non-differentiable graphs. The continuous functions but non-differentiable at some points or every points may be characterized via mean deviation function. The mean deviation function is the deviation of the mean function from the original function. It is differentiable and approximates the given non-differentiable function. This is a new type of characterization of unreachable graphs. Since ECG graphs are continuous everywhere but non-differentiable at a few number of points thus in this paper we have used this new methodology to find some distinguishable measurements of left ventricular hypertrophy by comparing normal and problematic ECGs.
