[Accelerated exercise test for the evaluation of transesophageal cardiac pacing].
The diagnostic potentialities of the unique procedure of transesophageal cardiac pacing (TECP) exercise test were examined. The accelerated one-stage TECP test was started just at a rate equal to the heart rate submaximal for a patient's age, and continued up to 1 min. The test was considered to be positive with horizontal or obliquely descending ST segment depression greater than or equal to 2 mm. The procedure was used to examine 116 patients: 75 with coronary heart disease and 41 with neurocirculatory dystonia. A high (93 versus 84%) diagnostic sensitivity was displayed by the proposed modified exercise test versus the graded test. Noteworthy, it is possible to substantially reduce the duration of exercise test (1 min versus 5-7 min of the graded test). The accelerated TECP test is safe for patients, easy-to-use and fails to cause any complications.
