  • Activity of the autonomic nervous system and diastolic disfunction of the left ventricle in hypertensive patients
    Klemenc, Matjaž, 1960- ...
    In our study we tried to elucidate the relationship between the changing compliance of the left ventricle and the tone of the autonomic nervous system (ANS). ANS activity was determined by spectral ... analysis (SA) of R-R interval variability (FFT). The 2-D guided M-mode echocardiogram was performed in orderto measure dimensions of the left ventricle. Pulsed wave Doppler was usedto obtain peak velocity flow through the mitral valve (i.e. E and A wave).SA showed a significantly lower value of HFžLF area ratio in hpertensivepatients (p=0.01). 26.2% of hypertensive patients had a significantly lower value of this ratio, 39.7% had significantly lower value of E/A ratio, and 12.5% had at the same time significantly lower E/A and HF/LF.
