Esophageal P-synchronous pacing.
An esophageal electrode can be employed to provide atrial sensing which then can be used to change from temporary right ventricular (VVI) pacing to P-synchronous (VAT) pacing. Two cases of postoperative aortic valve replacement, each with new complete heart block (CHB) and dopamine dependency, are presented. In both cases, establishment of P-synchronous pacing resulted in improved hemodynamic status characterized by successful weaning from dopamine and maintenance of adequate cardiac output (CO).
