Normal Values for Echocardiographic Parameters
Disease description:
Sometimes my heart rate suddenly becomes very fast, and breathing feels slightly labored. I had an echocardiogram, which indicated regurgitation. What are the normal values for echocardiogram parameters?

Echocardiography with color Doppler, also known as color Doppler ultrasound of the heart, is a non-invasive cardiac imaging technique used to evaluate cardiac structure and function. It involves numerous parameters, mainly including the following:
1. Interventricular septal thickness (IVS): The normal range is generally 7-12 mm; values beyond this range may suggest hypertrophic cardiomyopathy.
2. Left ventricular posterior wall thickness (LVPW): The normal value is approximately 6-10 mm; thickening may be associated with diseases such as hypertension.
3. Left ventricular end-diastolic diameter (LVEDD): Approximately 45-57 mm in males and 42-54 mm in females; abnormalities may reflect ventricular dilation or constriction.
4. Ejection fraction (EF): 50%-70%, representing the percentage of blood pumped out of the ventricle during each heartbeat relative to the end-diastolic volume.
5. Left ventricular ejection fraction (LVEF): 55-80%, specifically assessing left ventricular function.
6. Mitral valve inflow velocity: 0.3-0.9 m/s, an important parameter for evaluating valve function.
