Ethical issues with ECGs: ECGs can be a very powerful diagnostic tool. However, they can occasionally yield misleading or false information. Taking drugs such as warfarin can prevent life thretening blood clots from forming. But, if it's taken in the wronge dose it can cause fatal bleeding.
Doctors may occasionally decide it's inappropriate to diagnose and/or treat patients:
1. If it's against someone's religion or belief system,
2. If it's against a patients wishes, or
3. If there's no benefit to the treatment, or the side effects outweigh the benefits.
