RESUMO
A novel impedance cardiograph event detection method using wavelet transform is proposed. When compared to the C and E points in the pressure-volume loop, the wavelet method performs significantly better than the traditional method (P < 0.05) in the B and X points detection even after the addition of 20% artificial noise into the test signal. Nevertheless, the SVs estimated by ICG are poorly correlated with values measured by the conductance catheter.
