Descending on the arrival we noticed a small amount of smoke coming from the First Officer's windshield heat terminal.  We donned the oxygen masks and established communications with each other.  I turned the windshield heat off immediately and the small amount of smoking stopped simultaneously.  No further indications there was an overheating situation (terminal was not hot; no smoke or odor existed).  The entire event lasted no longer than 5 seconds.
