An esophageal electrode can be employed to provide atrial sensing which then can be used to change from temporary right ventriculor (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 adequafe cardiac output (CO).
