There is a significant error in the wording on the Pacemakers page (page 110) regarding the set up of a transcutaneous pacemaker.

This section should read:

• should be set to non demand mode when there is no organised rhythm
• set to demand mode if no there is an organised rhythm as this prevents pacing on Q wave that can precipitate ventricular tachyarrhythmias

This error will be corrected in the online version with the next upload of files.
