Annie Thorisdottir Suffered a Heart Arrhythmia During CrossFit Games Event ‘Chaos’

Statement from Annie Thorisdottir

“Absolutely LOVED that event!! I was so happy when I finished the pistols and got to the box at that point I knew the workout was mine! I’ve been hoping for those high box jumps ? 

But then something I’ve had to manage since I was a teenager , a heart arrhythmia, set in on box jump number 5 – this happens in training maybe 3-4 times through the year and I have not wanted to get a surgery done – this has never happened during competition, but today it did. It’s scary when you’re no longer in control and with this many fit ladies around me, resting didn’t seem like an option. I think it might have been the impact from the box jumps that caused it, and two more episodes happened before finishing my 25th rep. 

Sometimes things don’t go the way you’d want them to but only thing you can control is how you react to it.”


Heart rhythm problems (heart arrhythmias) occur when the electrical impulses that coordinate your heartbeats don’t work properly, causing your heart to beat too fast, too slow or irregularly.

Heart arrhythmias (uh-RITH-me-uhs) may feel like a fluttering or racing heart and may be harmless. However, some heart arrhythmias may cause bothersome — sometimes even life-threatening — signs and symptoms.

Heart arrhythmia treatment can often control or eliminate fast, slow or irregular heartbeats. In addition, because troublesome heart arrhythmias are often made worse — or are even caused — by a weak or damaged heart, you may be able to reduce your arrhythmia risk by adopting a heart-healthy lifestyle.


Arrhythmias may not cause any signs or symptoms. In fact, your doctor might find you have an arrhythmia before you do, during a routine examination. Noticeable signs and symptoms don’t necessarily mean you have a serious problem, however.

Noticeable arrhythmia symptoms may include:

  • A fluttering in your chest
  • A racing heartbeat (tachycardia)
  • A slow heartbeat (bradycardia)
  • Chest pain
  • Shortness of breath
  • Lightheadedness or dizziness
  • Sweating
  • Fainting (syncope) or near fainting
