    【Abstract】 AIM: To name the basic waves of reconstructed impedance differential cardiogram, and to investigate the amplitude and time interval of the waves. METHODS: The main waves of the reconstructed impedance differential cardiogram of 180 healthy adults were clarified and studied on their characteristics. The amplitude and interval of those waves were calculated statistically. RESULTS: The AO′, PL′ and PR′ were constituents in blood vessel, and each of them had C wave in a positive direction, X wave in a negative direction and O wave in a positive direction or a negative direction. The LV′ and RV′ were constituents in ventricles of the heart, both of them had b wave in a small positive wave, C wave in a negative wave and O wave in a positive direction. The amplitude of C wave in constituent of AO′ was the largest, that in constituent of PL′ or PR′ was the second, and LV′ or RV′ was the smallest. The QC interval of constituent in ventricles exceeded that in blood vessel. CONCLUSION: The research offers a basis for the clinical application of reconstructed impedance differential cardiogram. ......
