I Have a Pacemaker

This shouldn't be a problem

 

Make sure that you take your pacemaker information with you.  When you go through the airport security you will need to show them this to prove you have a pacemaker.  They will then hand search you rather than you walking through the magnetic metal detector.

 

Whilst you are on holiday just avoid getting close to anything with a large magnetic field as it can disrupt the settings or disable your pacemaker.
