Ward (12-9-3) stopped all three shots he faced in the shootout. Carolina improved to 2-4 in the tiebreaker this season. St. Louis fell to 3-3.
Brandon Sutter gave the Hurricanes a 1-0 lead in the third period, but defenseman Alex Pietrangelo's power-play goal tied it.
Both teams missed on their first two attempts in the shootout. Ward stopped Alex Steen on the Blues' third try, setting the stage for Jokinen's winning goal. Jokinen beat Jaroslav Halak with a backhanded shot over the goalie.
Sutter broke the game's scoreless tie 3:18 into the third period when he broke in alone on the right wing and lifted the puck between Halak's pads for his sixth goal. Pietrangelo tied it with 13:29 left in regulation.
Halak, who stopped 28 shots, halted Eric Staal on a breakaway with 11 seconds left in overtime.
St. Louis had a 5-on-3 power play for 80 seconds late in the second period, but couldn't score.
