A digital filter for thoracic impedance cardiography was developed and implemented on a 16-bit personal computer after examining the effect of respiratory movement on the first derivative of the thoracic impedance signal. Four male subjects exercised with a cycle ergometer at 100 and 150 W successively, after resting for 5 min. Thoracic impedance and its first derivative (dZ/dt) were recorded by a standard four-electrode cardiograph. The peak-power spectral densities of the pneumogenic (P/sub p… CONTINUE READING
