High frame rates are needed to avoid underestimating myocardial velocities; hypothesis-generating for standardized protocols in clinical echocardiography.
Does reducing the sampling rate of tissue velocity imaging affect the accuracy of myocardial velocity measurements in healthy individuals?
A minimum frame rate of 70-100 frames/s is required for accurate tissue velocity imaging measurements to prevent significant deviation and underestimation of peak velocities.
Lind et al. (2002) studied this question.
