Overview

Should not yet change practice; hypothesis-generating for acoustical heart disease diagnosis.

Structured PICO

I
Intervention
Constraint least-square approach for tracking heart wall movement based on phase and magnitude of demodulated signal
O
Outcome
Detection and measurement of small vibrations of the heart wall (<100 µm amplitude) in the frequency range up to several hundred Hertzsurrogate

A novel constraint least-square method enables accurate, noninvasive transcutaneous measurement of minute heart wall vibrations, providing a potential new tool for acoustical diagnosis of heart disease.
