Detecting point with anomalous Z value on a 3D poliline

Help: How can I detect ( on automatic way) the points on a 3D poliline/linestring element where the Z value is higher than a certain value (parametrizable) from the previous point on the poliline?

Is a GM feature doing this?
I need an script?

Now  I export to XLS, make the difference on 2  next Z values, and make a filter on XLS where DIFERENCE is higher than .....  Something much time consuming.

Thanks a lot
