[Is there an alternative to traditional stress tests? (One more time about transesophageal cardiac pacing)].
OBJECTIVE
To assess diagnostic potential of transesophageal cardiac pacing in patients with ischemic heart disease.


METHODS
One hundred patients with overt or suspected ischemic heart disease (IHD) unable to perform or complete standard exercise test.


METHODS
In addition to clinical investigation and transesophageal cardiac pacing stress Doppler echocardiography was carried out in 60 and coronary angiography in 30 patients.


RESULTS
Transesophageal pacing was completed in 95% of patients. Sensitivity of the test for diagnosis of IHD was 85%, specificity--77%, predictive value of positive and negative results--95 and 73%, respectively. Combined use of transesophageal pacing and Doppler echocardiography increased sensitivity of diagnosis of IHD up to 92%. Blood pressure increment during transesophageal pacing did not exceed 10 mm Hg.


CONCLUSIONS
Transesophageal cardiac pacing is a highly informative, simple, safe and widely available selective stress test. Results of this test does not depend on concomitant pathology and physical fitness of a patient. Therefore it presents an alternative to standard stress tests and is a method of choice in many diagnostic situations.
