Abstract
Regress of myocardial ischemia during atrial stimulation was observed in 10 of 106 patients (9,3%) with positive atrial pacing stress test. Seven of these patients had minimal coronary artery lesions (group A) and 3 had critical stenoses of left anterior descending artery (group B). Proposed mechanisms of ischemia regression were alleviation of str ess induced transient coronary spasm in group A and opening of dormant at rest collaterals in group E. For improvement of sensitivity of atr ial pacing a additional test with ''sudden stress'' is suggested.
