Resting ECG (as a Screening Test)
Last reviewed 25 August 2026 · Evidence-graded review — see Methodology
Twelve leads, five minutes, and a reassuring strip of paper at the end. In someone with symptoms or known heart disease an ECG is genuinely informative. As a screen in an asymptomatic, low-risk adult its main product is borderline findings, and borderline findings lead to more tests.
Curry SJ, Krist AH, et al. (US Preventive Services Task Force) “Screening for Cardiovascular Disease Risk With Electrocardiography.” JAMA 2018;319:2308–2314 recommends against screening with resting or exercise ECG in asymptomatic adults at low risk of cardiovascular events (Grade D), and finds the evidence insufficient at intermediate or high risk (Grade I). The reasoning is not that the ECG is inaccurate but that the cascade it triggers — stress testing, angiography — carries real harm in exchange for very little yield.

Not covered in the current review
Singapore’s national screening committee has not reviewed this test in the current volume of its report, which covers nine conditions. That is not a verdict either way.

What you would actually pay
- Healthier SG
- Not subsidised
- MediSave
- Not among the screenings named for outpatient claims

What it costs when it is wrong
- Basis
- No published harm criterion found
- Severity
- Not documented
Not covered in the current volume of the committee’s report, so no harm criterion was found either way.
An empty finding, not a clean bill of health: this means nothing documented was found for this test. It is not a claim that the test is safe.
Screening harm is not only a laboratory question: the committee’s own criteria advise against a test when “the screening test, or follow-up tests arising from a positive screen, are associated with significant medical risks”. Sources on overdiagnosis → · How this is graded.
FAQ
Is the Resting ECG (as a Screening Test) worth doing in Singapore?
For adults without symptoms, Resting ECG (as a Screening Test) sits at the weak grade on our evidence scale. It typically costs S$40–80 in Singapore.
