From the Research

To convert Doppler slope from seconds to meters per velocity (m/s) to millivolts per ampere (mVA) is not a standard or valid conversion in the context of echocardiography or Doppler ultrasound, as Doppler slope is typically measured in seconds and represents the time it takes for blood flow velocity to increase. The provided evidence does not support a direct conversion from Doppler slope in seconds to millivolts per ampere (mVA) 1, 2, 3, 4, 5. The Doppler slope represents the time it takes for blood flow velocity to increase, typically measured during mitral valve assessment. The conversion formula for acceleration (m/s²) is: acceleration (m/s²) = 1/slope (seconds), but this is not relevant to the conversion to millivolts per ampere (mVA) 1. For example, if the Doppler slope is 0.08 seconds, the acceleration would be 1/0.08 = 12.5 m/s², but this does not provide a conversion to millivolts per ampere (mVA) 2. This measurement helps clinicians evaluate diastolic dysfunction and can provide insights into left ventricular filling pressures and overall cardiac function, but it does not involve a conversion to millivolts per ampere (mVA) 3, 4, 5. In clinical practice, the Doppler slope is used to assess mitral valve area and left ventricular diastolic function, but the conversion to millivolts per ampere (mVA) is not a standard or valid application of this measurement 1, 2, 3, 4, 5.
