Not at high risk.
Thank you for using Healthcare Magic. The anesthesia
for your colonoscopy
is likely to be sedation or possibly general anesthesia. I advise you mention to the doctor that you have PVCs and the doctor may wish to do a ECG. This may or may not show PVCs but will be a baseline prior to your colonoscopy. If you take atenolol
frequently then I suggest you take a dose in the morning. The anesthesia whether sedation or general anesthesia is unlikely to make the PVCs any worse. You will be monitored throughout. If they do occur then there are a number of drugs which can easily be used to treat an episode. You are not a high risk of any cardiac complications. I am confident that you will not have a significant problem during the colonoscopy.
I hope this is of help. If you have any further questions, please do not hesitate to contact me.
