Intraoperative unipolar and bipolar ventricular electrograms reliably delineate damaged myocardium, offering advantages over the dye technique in patients undergoing cardiac surgery.
Does obtaining unipolar and bipolar ventricular electrograms at surgery improve the delineation of damaged myocardium compared to dye techniques in patients undergoing cardiac surgery?
Intraoperative unipolar and bipolar ventricular electrograms provide a reliable and reproducible alternative to dye techniques for delineating myocardial damage during cardiac surgery.
Absolute Event Rate: 0% vs 0%
A technique is described for obtaining unipolar and bipolar ventricular electrograms at surgery. The alterations in the form of the electrogram in various pathologic states are consistent, reliable, and reproducible. The method has advantages over dye technique for delineating areas of damaged myocardium and has been used in a clinical series of 12 patients undergoing cardiac surgery.
