ECG recording in primary care: is it done correctly?

The ECG is the most commonly performed cardiac investigation but incorrectly recorded ECGs may lead to misdiagnosis. In this study, questionnaires were used to assess the pre-training perceived and actual knowledge of correct ECG recording technique among 54 primary care staff. Training was then performed and, after training, many staff admitted that their previous practice had been incorrect some or all of the time and said that they would change their practice.
