Full textObjective: To establish the measurements of normal tricuspid valve flow velocities at 11 to 13 weeks and 6 days to determine E-wave, A-wave, E/A ratio, cardiac cycle length, diastole length, diastole/cardiac cycle ratio, and their relationship with gestational age, nuchal translucency thickness, the characteristics of the study population, and to assess the reproducibility of flow measurements. Methods: Between February, 2006, and August, 2008, a total of 166 women with a singleton normal pregnancy between 11 and 13 + 6 weeks of gestation consented to participate in the study. Analysis of the waveforms consisted of calculation of peak velocity (cm/s) of the E-wave and A-wave, E-wave/A-wave ratio, cardiac cycle length (ms), diastole length (ms) and diastole/cardiac cycle ratio. To evaluate the intraobserver and interobserver agreement, a subgroup of 12 patients, chosen randomly, was examined twice by each examiner. For descriptive analysis of the results were calculated average and standard deviation. Simple and multivariate linear regression was used to establish the correlation between dopplervelocimetry among parameters and with gestational age, nuchal translucency thickness and the characteristics of the study population. Results: The average (± standard deviation) for transtricuspid flow-velocities waveforms parameters were: E-wave 25 (± 4.6) cm/s; A-wave 42.9 (± 5.9) cm/s; E/A ratio 0.58 (± 0.07); cardiac cycle length 390 (± 21.1) ms; diastole length 147 (± 18) ms; diastole/cardiac cycle length 0,38 (± 0.04). A statistically significant linear increase relative to gestational age was established for all parameters, except A-wave. Nuchal translucency thickness was not correlated with any parameter. A statistically significant negative regression coefficient was established for E-wave to maternal age (r=-0,18, p=0,04). A statistically significant relationship was established between: cardiac cycle length and diastole length (r=0.53; p<0.0001); diastole length and A-wave velocity (r=-0.15; p=0.05); E-wave and A-wave velocities (r=0.77; p<0.0001); E-wave velocity and D/C ratio (r=0.16; p=0.04); A-wave velocity and D/C ratio (r=-0.17; p=0.03). The intraclass correlation coeficients of interobserver and intraobsever evaluations (examiners 1 and 2) were: Ewave = 0.53 (0.53 and 0.64); A-wave = 0.45 (0.46 and 0.49); cardiac cycle = 0.70 (0.79 and 0.84) and diastole= 0.63 (0.85 and 0.82). Conclusions: These data determine normal parameters for tricuspid valve dopplervelocimetry and shows that these parameters, except A-wave, have positive correlation with gestational age, and good/moderate reproducibility.

Full textENGLISH ABSTRACT: This thesis investigates the feasibility of the laser Doppler vibrometer (LDV) for use in the autonomous auscultation of the human heart. As a non-contact measurement device, the LDV could become a very versatile biomedical sensor. LDV, stethoscope, piezoelectric accelerometer (PA) and electrocardiogram (ECG) signals were simultaneously recorded from 20 volunteers at Tygerberg Hospital. Of the 20 volunteers, 17 were confirmed to have cardiovascular disease. 3 patients with normal heart sounds were recorded for control data. The recorded data was successfully denoised using soft threshold wavelet denoising and ensemble empirical mode decomposition. The LDV was compared to the PA in common biomedical applications and found to be equally accurate. The heart sound cycles for each participant were segmented using a combination of ECG data and a simplicity curve. Frequency domain features were extracted from each heart cycle and input into a k-nearest neighbours classifier. It was concluded that the LDV can form part of an autonomous, non-contact auscultation system.
AFRIKAANSE OPSOMMING: Hierdie tesis ondersoek die haalbaarheid daarvan om die laser Doppler vibrasiemeter (LDV) vir die outonome beluistering van die menslike hart te gebruik. As 'n kontaklose meettoestel kan die LDV werklik 'n veelsydige biomediese sensor word. Twintig vrywilligers by die Tygerberg Hospitaal se LDV-, stetoskoop-, piësoelektriese versnellingsmeter (PV)- en elektrokardiogram (EKG) seine is gelyktydig opgeneem. Uit die 20 vrywilligers was daar 17 bevestigde gevalle van kardiovaskulêre siektes. Die data van drie pasiënte met normale hartklanke is as kontroledata opgeneem. Geraas is suksesvol uit die opgeneemde data verwyder deur 'n kombinasie van sagtedrempelgolf en saamgestelde empiriese modus ontladingstegnieke. Die LDV was vergelyk met die PV vir algemene biomediese gebruike en daar was gevind dat dit vergelykbare akkuraatheid het. Die hartklanksiklusse van elke deelnemer is gesegmenteer deur EKG data en 'n eenvoudskromme te kombineer. Frekwensiegebiedskenmerke is uit elke hartsiklus onttrek en in 'n k-naastebuurpunt klassifiseerder ingevoer. Daar is tot die gevolgtrekking gekom dat die LDV deel van 'n outonome, kontaklose beluisteringstelsel kan uitmaak.
