[Evaluation of the informative value and safety of the transesophageal atrial electric stimulation test in patients with unstable stenocardia and myocardial infarction (data of 24-hour ECG monitoring)].
The effect of the transesophageal pacing test (TEPT) on the occurrence of ventricular arrhythmias and ischemic episodes was examined on the basis of 24-hour ECG monitoring in patients with unstable angina (UA) and myocardial infarction (MI). It is demonstrated that TEPT is a relatively safe test for UA and MI patients (to be performed on day 10-14), which does not provoke severe arrhythmias during and after the testing, but for short paroxysms of ventricular tachycardia seen in 2-4% of the cases. Both painful and painless ST displacements were recorded during the test; ST elevation was only noted in MI patients. The time of ECG baseline recovery was longer in painful ischemic episodes, as compared to painless ones. The TEPT test is a valuable instrument for detecting latent atrioventricular conductivity disorders in UA and MI patients.
