In a previous paper, we reported the principle and electrical characteristics of capacitople-thysmography which is a method to detect thoracic plethysmograms by detecting capacitance change between insulated electrodes.<BR>This paper aims at confirming by animal experiments that this method detects the mechanical movement of the heart and haemodynamics in the heart or lung.<BR>An oscillator (100 MHz) is suspended a few centimeters above the thoracic cage (non-contact CPG) or set up on the thoracic wall (contact CPG) on an anesthetized dog.<BR>Non-contact CPG waves detect the resistive component of intrathoracic tissue. The detecting depth of contact CPG depends on the distance between electrodes. When the distance between electrodes is relatively large (10 cm), CPG waves reflect blood volume change in the heart or lung. At a relatively small distance between electrodes (4 cm), CPG is associated with the anterior wall movement of the heart.
