ON-LINE COMPUTERIZED ASSESSMENT OF CORONARY SINUS BLOOD FLOW BY THERMODILUTION.

Academic Article

Abstract

  • A computerized modification of the Ganz thermodilution coronary sinus blood flow technique is described. The computer assists in storage and retrieval of thermistor calibration constants, guides the operator through instrumentation set-up and operation via interactive displays, and computes and statistically processes 9-second increments of equilibrium coronary sinus blood flow data to yield estimates of mean coronary sinus blood flow. Time required for initial set-up and calibration is approximately 5 minutes; thereafter, repeat equilibrium flow determinations can be performed at one minute intervals. The method has been employed in over 60 patients to assess the effects on coronary sinus blood flow of various interventions, including atrial pacing, heparin administration, and glucose-insulin-potassium administration.
