Transesophageal Atrial Pacing during Echocardiography Exams

Left ventricular function in patients with ischemic heart disease at the moment of acute myocardial ischemia induced by transesophageal cardiac electrostimulation.

Savchenko AP, Smirnov AA, Liakishev AA, Mamytova ZZh, Abugov SA, Kozlov SG. Ter Arkh 1993;65(12):30-4. Repeat transvenous multiphase left ventriculography was performed in 14 patients with coronary stenosis diagnosed by clinical and angiographic findings. The procedure was conducted before and in the course of transesophageal pacing. The latter provoked acute myocardial ischemia responsible for a wide range of left ventricular dysfunctions which are analyzed in the paper in terms of cardiomanometry parameters, cardiocycle energetic balance, diastolic function and local motions of the camera walls.
