Why can orogastric intubation cause heart arrhythmia? I'm a medical student and I can't find the answer Sorry if it's not the right place for asking

The real life answer is that this is extremely rare. Having done thousands of upper endoscopies with heart monitoring, I have never seen it. Still must be cautious though. Good luck with school!

You should discuss your particular case with your doc. Ablation may be a possibility. Read more...
