title: [The possibility for the presumed detection of the obstructive lesion of the coronary arteries in stenocardia patients by the data from circadian ECG monitoring and stress tests].
abstract: Whether 24-h ECG monitoring (ECGM) may be used in detection of multiple arterial obstructions in anginal patients and to compare diagnostic efficacy of ECGM and bicycle exercise (BE) in prediction of 2 or 3 lesions was investigated in 137 patients subjected to ECGM and selective coronarography. 117 of them did bicycle exercise. The number of episodes of painful and painless myocardial ischemia in ECGM was related with the extension and depth of the coronary flow obstruction. The overall index of myocardial ischemia has been estimated warranting higher probability of detection of subjects with obstruction in 1 or more coronary arteries. Sensitivity and prediction value of ECGM was similar to those of BE, but the latter was more specific.
