What is the normal MV velocity range?

Explanation:
Normal MV velocity refers to the peak transmitral inflow velocity measured across the mitral valve during early diastole (the E wave) with Doppler. In a healthy adult, this early diastolic filling velocity typically falls between about 0.6 and 1.3 m/s. Therefore, the full range 0.6–1.3 m/s best represents the normal window; values below 0.6 may indicate impaired LV relaxation or reduced diastolic function, while values above 1.3 can be seen with higher filling pressures or certain diastolic abnormalities. The narrower ranges miss part of the normal spectrum, which is why the broader 0.6–1.3 m/s range is the correct choice.
