Welcome to icliniq.com.
I guess you must have undergone echo in order to find out the cause of atrial fibrillation.
Now, regarding your doubt, as such the risk of stroke is not high in you so blood thinners are not absolutely necessary for you. Now, if AFib is of less than 48 hours duration, then we do not need blood thinners to be started so long prior to cardioversion and we directly proceed with cardioversion with blood thinners started just before. So if you are able to access healthcare facility within this time then such long blood thinners may be avoided. Also, even if you remain in AFib throughout the holiday, it is not life-threatening.
Next thing, regarding the strategy mentioned by you, this is not approved by any guidelines or authority. But, yes, it can be adopted and no harm in that, but I or any other medical personnel cannot advise such strategy to save the holiday as there is no medical ground for that. Also, If you are planning some risky activities which may involve injuries then it will increase the risk of bleeding. So you need to consider all these factors.
