Last night’s post season Vikings vs. Saints game was so thrilling and intense, many Apple Watch users received warnings about abnormally high heart rates, a potential precursor to a heart attack.

Along with watchOS 4, Apple included improved health monitoring features, like alerts when a user’s heart rate seems abnormally and dangerously high, particularly during inactivity.

Last month, we reported on an amazing story about how the feature saved one man’s life. However, last night a lot of users tricked their Apple Watches during the Vikings-Saints game (via BGR).

In what may be one of the NFL’s most exciting post-season games, Vikings quarterback, Case Keenum made a 61-yard throw to Stefon Diggs, who scored the winning touchdown with zero seconds left on the clock (NFL playoff first).

Apple Watch users started sharing on Twitter about their heart rate jumping over 120 BPMs while being “in-active” during the intense game. One user even shared he received two alerts.

9to5Mac’s Zac Hall (who is an avid runner and Saints fan) even noticed the same the heart rate jump during the game. How about you? Did your Apple Watch warn you about the dangers of such an intense game?
