title: Considerations in placement of right internal jugular cannulas.
abstract: This case report describes a patient who had paroxysmal ventricular bigeminy of an unrecognized etiology. After 24 hours of observation, it was noted that the patient's head position correlated with the bigeminy. A single-lumen infusion catheter, which had been placed through an internal jugular cannula, was transduced and demonstrated a ventricular pressure waveform. This catheter was removed and the ectopy resolved. The factors associated with this arrhythmia are discussed.
