The hardest thing to avoid is a security wand which some places use as an alternative to the "doorway" type - it took me hours to get into Farnborough Airshow as the "doorway" type alarm was set off by my pacemaker and I refused to let them wand directly onto it - even offered to strip to get round the impasse but eventually a security manager saw sense.My brother had a pacemaker fitted. I know he was well schooled in what to avoid. But nevertheless, itβs good to improve recognition.
