Echocardiogram (2D Echo)
An ultrasound scan of the heart that shows its chambers, valves and how well it pumps.
Quick Summary
To check heart pumping (ejection fraction), valves, heart failure and birth defects.
Chamber sizes, wall movement, valves and pumping function.
No preparation for a standard echo.
Overview
An echo is the main test for heart failure and valve disease.
It uses no radiation.
What It Measures
Ejection fraction
How much blood the heart pumps each beat.
Valves
Narrowing or leaks.
How It's Performed
- 01
Position
Lie on your left side.
- 02
Scan
Gel and probe on the chest for 20–40 minutes.
- 03
Afterwards
Return to normal.
Reference Ranges
Note: Normal ranges vary by laboratory. Consult your report for the specific reference used.
| Parameter | Typical Range (Adult) | Units |
|---|---|---|
| Ejection fraction | 55–70 | % |
Interpreting Results & Next Steps
Discuss with Doctor
Your doctor will explain the report and what happens next.
If values are Low:
A low ejection fraction means the heart isn't pumping as strongly as normal.
