What should be done when a diagnosis of ACS is in doubt?
When a diagnosis of ACS is in doubt, healthcare professionals should consider taking serial resting 12-lead ECGs, reviewing previous resting 12-lead ECGs, and recording additional ECG leads. Clinical judgement should be used to decide how often this should be done, and note that the results may not be conclusive. Healthcare professionals should also obtain a review of resting 12-lead ECGs by a qualified healthcare professional.
