Table 5 Accuracy of PHU and physical exmination

From: Cardiac assessment accuracy by students using palm-held ultrasound compared to physical examination by skilled cardiologists: a pilot study with a single medical student

  PHU vs TTE (95% CI) PE vs TTE (95% CI)
Ejection fraction (%)* 68.8% (57.8–78.1%) 67.2% (55.0–75.5%)
Mitral regurgitation 88.3% (79.0–93.9%) 92.2% (83.7–96.7%)
Mitral stenosis 96.1% (88.7–99.1%) 98.7% (92.3–100%)
Aortic regurgitation 90.9% (82.1–95.8%) 98.7% (92.3–100%)
Aortic stenosis 88.3% (79.0–93.9%) 93.5% (85.3–97.5%)
Pericardial effusion 90.9% (82.1–95.8%) 92.9% (83.7–96.7%)
