How should ultrasound dynamics of the heart geometry be assessed?

The level of error of test-retest reproducibility of the obtained findings is within the ranges of a permissible error of test-retest type for M and 2D techniques. The suggested method of a simple mathematical processing allows to reduce probability of test-retest error. To make mathematical processing correct, the interval between ultrasound investigations should not be < 12 months. The reported method is a simple one and can be used in every day practice when it is necessary to assess the shifts using the findings of repeated examinations.
