Background:

Acoustic quantification (AQ) is a noninvasive technique for real-time left ventricular (LV) area/volume waveform analysis.
The filling phase of the LV waveform is crucial for evaluating diastolic properties.

Purpose of the Study:

To demonstrate the utility of signal-averaged AQ curves for enhancing LV waveforms.
To enable reliable, quantitative, and automated analysis of diastolic function using AQ.
To assess diastolic dysfunction in patients with LV hypertrophy and hypertension.

Main Methods:

Utilizing signal-averaged acoustic quantification (AQ) to enhance left ventricular (LV) waveforms.
Automated detection of diastolic phases from processed LV waveforms.

Calculation of diastolic performance parameters from signal-averaged AQ data.

Main Results:

Signal-averaged AQ analysis allows for easy detection of diastolic phases.
Quantitative parameters of diastolic performance can be reliably calculated.
AQ has been successfully applied to identify diastolic dysfunction in specific patient groups.

Conclusions:

Signal-averaged AQ analysis complements traditional LV AQ analysis.
This method offers a reliable and automated approach to assess LV diastolic function.
Age-dependent normal values and reference ranges are forthcoming for these parameters.
