Abstract
Presents a new procedure of P-waved triggered signal averaging ECG and its utility for paroxysmal atrial fibrillation (PAI) risk assessment in patients (pts) suffering from mitral valve disease (MVD). A study was performed in 20 MVD-pts with PAF, in 10 MVD-pts without PAF and in 10 healthy subjects. Time-domain analysis after filtration 25-250 Hz and 40-250 Hz provided the following parameters: P complex duration (PD), RMS of total P complex (RMSP) and of its terminal 10, 20 and 30 ms. FFT frequency-domain analysis, performed on the 120 ms segment, provided for each X, Y or Z lead the percentage ratio of spectral areas at bands: 20-50/0-20 Hz (AR1) and 60-120/0-120 (AR2). At 40-120 Hz filtration all time-domain variables significantly differed for MVD-PAF(+)-pts from PAF(-) subjects. Frequency analysis showed that ARI was significantly higher in PAF(+) than in the remaining examined subjects without PAF.<>
