Just had a letter from hospital advising me that I will be having an internal cardiovertor defibrillator (ICD) implanted shortly, for AF. I have a pre-op on 3rd June . Also see the arrhythmia nurse on 29th May. I didn't realise that an ICD was used for AF, guess I was wrong. My EP cardiologist said, if this doesn't sort it out, I'll have to have an ablation, too. I certainly hope this IS going to help me!
