Abstract A computer-based system has been developed that enables the continuous measurement of cardiac output at rest as well as during exercise. The respiratory and motion artefacts appearing in the first derivative of the transthoracic impedance change (dZ/dt) were eliminated by adopting an ensemble averaging technique. A sufficiently high correlation was observed between cardiac outputs determined by the impedance and CO2 rebreathing methods. The system may facilitate the physiological investigation of cardiac function during exercise.
