I had achilles tenodon surgery 1 week ago and started having heart palpitations yesterday. They are not constant but very frequent. Not a racing heart beat but skipped beats or extra beats is what I feel. I am not dizzy with this nor do I feel faint. I was able to sleep last night but each time I awoke, I did feel the fluttering. I have been taking Oxycodone for my pain, but yesterday I only took 5mg early in the morning and no more, and none today. My pain is basically gone. But for 3-4 days or so I took between 20mg-10mg Q 4-6 hours. I was wondering if the oxy could be the cause?
Thanks for your question on Chat Doctor. I can understand your concern. No, oxycodone can not cause heart palpitations. So this is not a cause for your symptoms. Sometimes, few patients do get cardiac arrhythmia (rhythm disturbances in heart) after surgery. And this can cause palpitations. So we should first rule out arrhythmia in your case. So get done ECG, 2d echo and Holder monitoring (24 hour continuous monitoring of ECG). If all these are normal then no need to worry about arrhythmia. Stress and anxiety related to surgery can also cause similar symptoms. So consult psychiatrist and discuss all these. You may need anxiolytic Chat Doctor.  Don't worry, you will be alright, first rule out heart diseases. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
