Abstract

Two new implantable sensors for blood flow measurements were examined. The first sensor determines the change of conductivity of blood on shear forces, while the other is based on the measurement of the resistance of a heated resistor. Both hemodynamic sensors were implanted in dogs in the coronary sinus, the vena cava superior and the right outflow tract. The sensor signal was measured during electrical stimulation of the heart and during atrial and ventricular fibrillation. The results confirm that both sensor principles offer information about blood flow and cardiac output.
