COMBINED TRANSESOPHAGEAL 2-DIMENSIONAL DOPPLER-ECHOCARDIOGRAPHY AND TRANSESOPHAGEAL ATRIAL-PACING - APPLICATIONS IN CORONARY-ARTERY DISEASEAND TACHYARRHYTHMIAS

Combining transesophageal two-dimensional Doppler echocardiography and transesophageal atrial pacing provides a new alternative technique ca pable of assessing: (i) pacing-induced left ventricular wall motion ab normalities; (ii) pacing-induced ischemic mitral valve regurgitation; and (iii) diagnosis and therapy of supraventricular tachyarrhythmias. We report the background, principles, and clinical uses of this newly developed technique combining transesophageal two-dimensional Doppler echocardiography and transesophageal atrial pacing. Furthermore, the i nitial results in 95 patients studied between April, 1990, and Decembe r, 1991, are presented.
