Hi. I was having INR checked when the nurse asked if I had heard about the new device which is implanted to control AF. Very recent trials. Having just had av node ablation (Oct) was angry with myself for having it done. If this is fact why oh why didn't EP tell me to wait awhile instead of urging me to have AV node ablation. Has anyone heard of this? Presuming nurse has correct facts. Sunigirl.
