I am looking at this sign from the Brazilian Sign Puddle and I can't figure out 
how to reproduce the movement.

The Left hand looks as if it is flat, just above the shoulder, parallel to the 
body, touching twice.

Below, apparently a right hand is moving foreward twice.  Is that the movement? 
Without a drawing I cannot be sure. 

It could be a heartbeat, with the left hand patting, and the right fist bulging 
out, but it feels really awkward because the movement arrows for the right hand 
feel at a glance as if they are poking the person from behind. 

The surface symbol seems out of place.
