Analysis of correlations between components of left sided reflected high intensity motion signals and age

Background: We have shown previously, that analysis of dopplerographic left sided reflected high intensity motion signals (RIMS) can become a new simple and effective approach for assessment of left ventricular (LV) systolic and diastolic function. In this study we decided to analyze correlations between velocity parameters of systolic (Sa) and diastolic (Ea and Aa) components of RIMS and age. Material and methods: 90 healthy subjects between 20 and 80 years of age underwent dopplerechocardiographic exam. RIMS were recorded from 4-chamber apical view, when the sample volume was placed in projection of pulmonary…
