Simultaneous transesophageal atrial pacing and transesophageal echocardiography in cardiac surgical patients.
To measure the effect of inserting a transesophageal echocardiography (TEE) probe on the pacing threshold of a previously inserted transesophageal pacing stethoscope, and to examine whether an indwelling pacing stethoscope influences the feasibility and image quality of a TEE examination. ⋯ Placement of a TEE probe results in a modest increase of the transesophageal pacing threshold. An indwelling pacing stethoscope frequently interferes with the ability to perform a full echocardiographic examination, and probe manipulation commonly causes loss of pacing.
