After having problems with palpitations for months with all the usual symptoms of blurred vision and chest pain. My cardiologist has said I have not suffered with af he checked my pacemaker and confirmed no af. Adjustments were made on the pacemaker to try and capture these events. So three months later at next pace maker check technician says the pace maker shows that I have been getting Atrial flutter now waiting to see consultant. Not sure what next step is but at least I now know what the palpitations were.
