Mitral Deceleration Time Unit Converter

Mitral deceleration time (DT) is a measurement taken during an echocardiogram that reflects how quickly blood flow across the mitral valve slows down during early diastole, the phase when the heart relaxes and fills with blood.

It is measured as the time interval from the peak of the early filling wave (E-wave) to its projected baseline. A normal deceleration time typically falls between 150 and 240 milliseconds.

This measurement helps clinicians assess how well the left ventricle relaxes and fills, making it a key indicator of diastolic function.

Mitral deceleration time is derived from blood flow across the mitral valve, which sits between the left atrium and left ventricle. The measurement reflects the interplay between left atrial pressure, ventricular relaxation, and ventricular compliance during early diastolic filling.
