| Aggregate Evidence Quality . | Grade B (Aggregate of Level of Evidence Equals B Because of Multiple Level of Evidence C References With Similar Findings) . |
|---|---|
| Benefits | Electrocardiography is less expensive than echocardiography or other imaging modalities for identifying LVH |
| Risks, harm, cost | Electrocardiography has a low sensitivity for detecting LVH |
| Benefit–harm assessment | The risk of concluding that a child with HTN does not have LVH on the basis of a normal electrocardiogram means that a diagnosis of end organ injury is potentially missed |
| Intentional vagueness | None |
| Role of patient preferences | Patients and families may prefer electrocardiography because of cost and convenience, but the sensitivity of the test is poor |
| Exclusions | None |
| Strength | Strong recommendation |
| Key references | 1,355–360 |
