Mikel Arteta's men looked to be on course for a huge victory after racing into a 4-0 lead after just 36 minutes.
Goals from Gabriel, Leandro Trossard, Martin Odegaard and Kai Havertz saw thousands of Hammers fans heading for the exit at the London Stadium.
But a quickfire double from Aaron Wan-Bissaka and Emerson Palmieri silenced the visiting Gooners, who feared a shock comeback could be on the cards.
Arsenal fans would have thinking of their 4-4 draw away at Newcastle in February 2011 where they became the first Premier League team to throw away a four-goal lead.
