Key result
A new ultrasound method using high-frequency digital sampling accurately measured small vibrations of the ventricle wall based on the Doppler effect.
Why the study?
Does a new high-sampling frequency Doppler ultrasound method accurately measure small local vibrations in the heart wall?
Does a new high-sampling frequency Doppler ultrasound method accurately measure small local vibrations in the heart wall?
A novel ultrasound-based method accurately measures small local vibrations in the heart wall by overcoming artifacts from large cardiac motion, offering potential for acoustical diagnosis of ventricular dysfunction.

May enable acoustical ventricular assessment; leaves open clinical validation before diagnostic use.
Kanai et al. (1993) studied Ventricular dysfunction. New ultrasound method for measuring small local vibrations was evaluated on Detection of small vibrations on the aortic wall and the interventricular septum. A new ultrasound method using high-frequency digital sampling accurately measured small vibrations of the ventricle wall based on the Doppler effect.
