Devices and methods are disclosed which relate to the detection of cardiovascular efficiency and risk of disease. The rate of volumetric change of the heart can be determined by measuring the parallel conductance across electrodes attached to the heart. Measurements from a lumen would consider the total conductance. The rate of volumetric or lumen cross-section area change can then be compared to an average model to determine the health of a patient.
