Nodal rhythm and electronic CVP monitoring

Nodal rhythm occurred after induction of anesthesia in a 65 year old man, with hemodynamic consequences. The use of electronic CVP monitoring allowed confirmation of the diagnosis, which was suspected from observation of the ECG tracing. The use of a water manometer would have caused overestimation of the intravascular volume status of this patient during the nodal rhythm. Electronic CVP monitoring allowed for the accurate determination of true ventricular filling pressure.
