Hello, I'm Linda. I hope you can help me. I'm due to go for pre-assessment tomorrow for a cryoablation. I've started with an AF attack this morning; if I'm still in AF tomorrow does that mean I will not be able to be assessed and will have to cancel the appointment? The last attack lasted 35 hours. I take Dronedarone and Bisoprolol. I haven't yet been given a date for the ablation and I'm afraid it will be delayed by this latest attack. Can anyone advise me please? Thank you.
