Well if the center horizontal line is at 0vdc then the arduino analog input pin will not be able to measure or detect that negative going pulse. In fact applying negative voltages to an arduino pin can damage it.

Does the triangle on the right represent ground or the trigger point? 

Why is there a "disconnect" near the far left graticule?

Your trigger point is set to -4V suggesting the entire signal swings negative.  Is that the case?
