P
Population
35 subjects (16 healthy volunteers and 19 patients referred for echocardiographic studies)
I
Intervention
Automated boundary detection with acoustic quantification technology
C
Comparator
Pulsed wave Doppler echocardiography
O
Outcome
Correlation of timing of events in the cardiac cycle and amounts of area change during rapid filling and atrial contraction between the two methodssurrogate
Automated boundary detection using acoustic quantification correlates well with standard Doppler echocardiography for assessing left ventricular diastolic function.
