I was quite excited to have ordered my Alivecor which came this morning but dismayed to read that it is not recommended for use by anyone with a pacemaker. After a lot of googling, I can't really come to a decision on whether to try it or just send it back. Has anyone any experience of using it when they have a pacemaker? I think the gist is that it might not show spikes - but it has in some trials. Any info appreciated.
